Questions and Answers

Selecting a filter fabric is an engineering decision based on seven critical parameters that ensure maximum efficiency and product longevity:

• Filtering solids from liquids or gases?
• The maximum allowable pressure drop across the filter media, as permitted by the process system.
• The size and distribution of the particles to be filtered; typically, the size threshold at which particles larger than this do not pass through the filter fabric.
• Filter fabric material: Does the filtered fluid and the material damage the polymer from which the filter fabric is made (dissolution, hardening, chemical degradation)?
• Operating temperature: Is the fabric’s material capable of withstanding the process’s operating temperature range?
• The technique for cleaning the fabric of filtered material.
• The replacement rate of the filter fabric – Is long-term durability required, or is the fabric replaced relatively frequently?

These are two different measurement methods for describing filtration density:

• Mesh: Indicates the number of holes per linear inch of netting. The higher the number, the denser the netting.

• Micron: An absolute unit of measurement indicating the maximum size of a particle that can pass through the fabric.

The difference lies in the fabric's structure and the method used to capture particles:

• Woven fabric: Made from warp and weft threads. Filtration occurs primarily on the surface. Suitable for wet filtration and for situations where the fabric needs to be lightly rinsed.

• Needle-felted fabric: A nonwoven fabric in which the fibers are compressed together. Filtration occurs deep within the fabric, enabling highly efficient capture of very small particles. This is the standard medium used for industrial dust filtration.

Absolutely. The main advantage of "Yanko Filtration" is its ability to produce solutions tailored to specific requirements:

• Custom sizes: We manufacture sleeves and filter media for all types of machines and equipment available on the market.

• Finishes and Seams: Hemming with snap rings, pleats, slip-on sleeves, or flaps, tailored to the customer’s existing design.

Yes. We manufacture filter fabrics that incorporate conductive fibers (such as carbon or stainless steel fibers).

• Why it’s critical: During the filtration of combustible dust or chemicals, static electricity is generated as a result of friction between the air and the particles in the fabric. Without controlled discharge of the static charge, a spark could be generated, leading to a dust explosion in the system. Antistatic fabrics are a mandatory safety component.

Both types of fabric are woven; the main difference lies in the structure of the yarn used to weave the fabric.

• In multifilament fabric, the yarn is woven from very fine fibers; filtration occurs both between the threads and among the fibers themselves. Typically, the pressure drop across the fabric during filtration is relatively high. The size of the filtered particles depends on the weave pattern, the number of weave layers, the thickness of the warp and weft threads, and the average number of fibers per woven thread. The performance of different fabrics is compared using the "permeability" parameter.
• In monofilament fabric, the base yarn in the weave consists of a single, uniform fiber. Filtration occurs exclusively between the fabric threads. In these fabrics, the particle size of the filtration can be “calibrated” through a process called calendering. The performance of different fabrics is compared using the nominal pore size parameter in microns.
  Monofilament fabric is characterized by a very high surface smoothness and minimal “cake” buildup of the filtered material on the fabric.

Special fabrics combine two types of fabric into one to provide unique filtration properties.

A glove box is a sealed, controlled workspace designed to create a complete separation between the operator and the manufacturing process. The goal is twofold:

• Operator protection: Preventing exposure to potent, hazardous, or aerosolized substances while working in a laboratory or factory.

• Material Protection: Safeguarding the product and preventing environmental contamination during the sampling or manufacturing of sensitive components.

The flexible cell offers a modern solution that combines safety with significant economic and logistical benefits:

• Availability and Delivery Speed: Thanks to advanced manufacturing methods and the fact that production takes place here in Israel, we are able to supply flexible glove boxes within significantly shorter lead times than is typical in the market. There is no need to wait months for imports from abroad or for the complex manufacturing of rigid boxes.

• Significantly lower cost: The purchase price of a flexible glove box is significantly lower than that of a rigid one. This solution provides the highest level of protection for both the operator and the material without straining the budget.

• Ergonomics and comfort: The flexible panels allow for a wide range of motion and maximum comfort for the operator.

• Logistics and cost savings:The unit folds up easily, saving on storage space and transportation costs.

• Operational efficiency:A flexible glove box allows for "single-use" operation, saving valuable setup time spent on washing and disinfecting between batches.

Absolutely. At Binko Filtration, we specialize in custom manufacturing, fully involving the customer in the design process. The enclosure can be manufactured in any shape or size, with glove positions and sleeve lengths customized, and with mounting points (such as metal rings or railing strips) designed to fit perfectly with the existing structure in your work environment.

An airlock is an "airlock" that serves as an intermediate space between the work area and the interior of the chamber.

• The advantage: It allows tools and samples to be inserted and removed without compromising the seal or exposing the interior of the chamber to the surrounding environment. The system is designed so that when one port is open, the other remains closed, ensuring continuous protection of the process.

Yes. Thanks to our flexible manufacturing process, we can design custom sleeves and openings tailored to accommodate measuring devices, sensors, and other components. We manufacture sealed "pass-throughs" that allow for the connection of electrical, vacuum, or data cables without compromising the required level of sealing in the chamber.

We select the construction material, in consultation with the customer, based on the chemical and physical requirements of the process:

• PVC sheets: A transparent, durable, and flexible material suitable for a wide range of standard applications.

• Anti-static PU (polyurethane): A material with exceptionally high mechanical strength that incorporates anti-static properties to prevent the buildup of static electricity—a critical factor when working with flammable materials or in sensitive work environments.

The answer has two aspects—engineering and economic:

• From an engineering perspective: Our cells are made from highly durable, high-quality materials, allowing for reuse provided the customer’s safety procedures permit it.

• From an economic perspective (cost versus benefit): In practice, most of our customers choose to use the booth as a one-time solution. The reason is simple: the costs of labor, the time required for thorough cleaning, the use of disinfectants, and the complex validation processes needed to confirm that the chamber is completely clean for the next batch are significantly higher than the price of a new chamber.

It is much easier, safer, and cheaper to buy a new unit than to invest in the resources required to clean and inspect a used one.

Industrial sewing is textile engineering. Unlike regular sewing, the focus here is on durability under extreme conditions:

• Equipment: Use of "heavy-duty" sewing machines capable of penetrating multiple layers of stiff fabric.

• Durability: The seams are designed to withstand mechanical stress, vibrations, chemical exposure, and high temperatures without coming apart.

• Precision: Each product is manufactured according to technical specifications and engineering drawings tailored to a specific machine in the factory

We use some of the most advanced technical fabrics in the world:

Glass fabrics, silicone- or Teflon (PTFE)-coated fabrics, Nomex/Kevlar fabrics for heat resistance, and antistatic PVC or PU sheets.
There is a very wide variety of fabric types available, and you can find the right fabric for any need.

We never compromise on seam strength. We use abrasion- and heat-resistant Kevlarthreads, PTFE (Teflon) threads that are resistant to acids and strong UV radiation, and, of course, polypropylene, polyester, nylon, and other types of threads—all in accordance with customer and product requirements.

The choice of fabric is based on the characteristics of the work environment:

1. Temperature: Is the fabric exposed to constant heat or to occasional splashes?

2. Chemical exposure: Is there contact with acids, oils, or harsh cleaning agents?

3. Mechanical wear: Is the product in constant motion or exposed to friction?

4. Standards: Is certification to a specific standard required? Examples include food contact, flame retardancy, antistatic properties, UV resistance, and more.

These are flexible solutions installed between two sections of piping or machinery:

• Expansion joint: Its function is to absorb changes in pipe length caused by heat or cold and to prevent cracks in the system. In addition, it is used to compensate for misalignment in the installation of rigid pipes or to bridge gaps between pipes that have some degree of movement between them.

• Bellows: A flexible joint with an "accordion-like" structure that allows for wide multidirectional movement while maintaining airtightness. It is used to protect pistons, mechanical arms, and air/material passages between vibrating machines.

Absolutely. We manufacture transition sleeves and connectors that can withstand temperatures of up to 1000°C. The sleeves are sewn from ceramic or glass fabrics and are designed for melting furnaces, chimneys, and industrial exhaust systems.

Yes. We manufacture sleeves and covers made from fabrics and sheets that meet quality standards for direct contact with food.
We also manufacture products designed to protect equipment on production lines.

Transparent "windows" made of flexible materials (such as durable PVC) can be incorporated into the sleeves or covers to allow operators to visually monitor the flow of material within the system without opening it, or to access control screens.

The most advanced solution available today is removable insulation jackets. These jackets are custom-sewn to fit the shape of the faucet, pump, or pipe.

The advantage: They significantly reduce heat loss (energy savings) and protect workers from burns. Unlike permanent insulation, they can be removed and reinstalled in seconds for maintenance.

This is a life-saving safety product. The flange guard is fitted over the connection between two pipes (the flange). In the event of a high-pressure rupture or leak, the guard stops the spray of hazardous liquid (acid, hot oil, or steam) and causes it to drip down in a controlled manner instead of spraying onto nearby workers or equipment.
A window can be incorporated, containing "Lakmos" paper designed to detect material leaks.

Absolutely. The major advantage of custom-made is design flexibility. Unlike off-the-shelf products that come in fixed sizes, we can custom-sew nets in any geometric shape required—triangles, trapezoids, or complex shapes tailored precisely to the anchor points in your garden or on your balcony.

The mesh density determines the percentage of light and radiation blocked:

• 60% shade nets: Designed primarily for agricultural use, allowing plenty of light to reach the plants.

• Shade nets with 90% or more shading: The recommended density for humans. They create deep, pleasant shade and provide significant protection from UV radiation for those beneath them.

Yes. We work with the highest-quality fabrics and mesh, including flame-retardant options. This is particularly important for installations in public institutions, kindergartens, schools, or locations near heat sources and barbecues.

The difference lies in three factors that determine the product's lifespan:

• Material type: We use fabrics with strong UV filters and an appropriate fiber thickness, specifically designed for Israeli sunlight.

• Stitching: Our stitching meets industrial standards, featuring reinforced edges and double-stitched seams that won’t fray in the wind. We will recommend the appropriate finish based on the customer’s needs.

• Durability: Cheap nets tend to fray or tear within a single season; our products are designed to last for years.

No. "Yanko Sifun" focuses on its core expertise: the specification, design, and manufacture of top-quality textile solutions. We provide the customer with a custom-sewn product ready for assembly according to the ordered dimensions, and the installation is carried out by the customer or a contractor on their behalf.

Absolutely. We can produce shade structures that include branding, logo printing, or custom graphics. This is an excellent solution for cafes, restaurants, or corporate events looking to combine a practical shading solution with prominent brand visibility.

Lifespan depends on the type of material and exposure to radiation:

• High-quality shade net: Provides effective protection for up to 4 years on average.

• Tarpaulin (PVC): A more durable and sturdy material that can last between 7 and 8 years, thanks to its greater resistance to wear and tear and sun exposure.

The field of automotive upholstery is at the heart of our family heritage. We represent the sixth generation of a tradition of sewing and manufacturing, with expertise passed down from father to son for 180 years. We combine this historical knowledge with modern materials to give vehicles a luxurious, durable, and precise look.

Car upholstery must be able to withstand extreme conditions that home furnishings do not encounter:

• UV resistance: Fabrics and sewing threads that do not fade or fray under the scorching Israeli sun shining through the windows.

• Abrasion resistance: Use of highly durable materials to withstand frequent entry and exit from the vehicle.

• Safety: Compatibility with airbag systems and the use of flame-retardant materials where necessary

No. Our expertise liesin technical textiles, automotive upholstery, and outdoor upholstery. We believe in focusing on the areas where we excel—high durability, outdoor conditions, and industrial needs—rather than standard interior furniture upholstery.

We use fabrics specifically designed to withstand outdoor conditions:

• Water-repellent fabrics: prevent liquids from being absorbed.

• Solushine fabrics: Extremely resistant to fading in the sun.

• PVC Tarpaulin: For applications requiring maximum water resistance and exceptionally easy cleaning.

The selection is based on the product's intended use:

• Seats: High-density foam (relatively firm) to prevent "sagging" and maintain comfort over time.

• Back/decorative cushions: Softer foam or flexible fillings that provide a soft feel.

• Protection (Sports): Shock-absorbing pads designed with a specific level of firmness to protect the user.

We manufacture upholstery designed to withstand heavy loads:

• Fitness Equipment: Repair and Reupholstering of Fabric Upholstery Designed to Withstand Sweat and High Mechanical Wear.

• Activity and gymnastics mats: Made with washable cover materials (such as canvas or vinyl) and soft, safe foam.

• Spa environments: Antibacterial fabrics that are resistant to high humidity and oils.

Absolutely. Thanks to our engineering expertise and local manufacturing capabilities, we produce activity mats, wall protectors, and sports mats in any size, thickness, or shape. The type of foam and the color of the cover can be customized to meet the customer’s needs, while ensuring a high-quality finish and maximum safety.
