Contrast powder
Fluorescent contrast powder
Fluorescent contrast powder is used for rapid and precise identification of leakage points in filtration systems. The fluorescent powder is filled into the filtration system, follows the path of least resistance and accumulates at leakage points. Ultraviolet light is then used to quickly and accurately identify the leakage and its cause.
Benefits
- Decades of successful application
- Easy to use
- Shortens downtime
- Helps reduce costs
Can be delivered from stock in different colours: yellow, pink, green, red, orange.
Packaging units of 1.5 kg or 4.5 kg.
UV lights
UV light is used to make the fluorescent powder glow as brightly as possible. Our custom-designed compact flashlight is one of the strongest of its kind.
- The LED output is comparable to that of a 150 W light.
- The beam is 15 times brighter than in regular LED lights.
- Inspection range of up to 6 m.
You can also obtain spare glasses from us.

Pre-coating powder
Are you having problems with wet, oily and sticky dusts and gases blocking your filter element?
WOKU pre-coating powder can boost the performance of textile and pleated filtration elements and protects the filtration element with its special structure.
The pre-coating powder is introduced into the filtration system when new filtration elements have been installed. It then forms a supporting filtration layer over the surface of the new filtration elements. This initial supporting filtration layer, consisting of a multitude of pores, prevents the ingress of dust particles into the filtration media and thus effectively prevents clogging or caking.
Benefits
- Increases the efficiency of your system
- Reduces caking
- Improves cleaning
- Can prolong service life
- Inert
- pH-neutral
- Safe and easy to use
Moreover, the pre-coating powder is lighter than the lime usually used and is not removed, or not substantially removed, from the filtration elements during cleaning.
Recommended doses:
- 250 g/m2 filter surface for filter bags/pockets
- 150 g/m2 filter surface for pleated filter cartridges/panels
Materials and equipment
We manufacture our products from high-quality needle felts, textiles and non- woven textiles. We have a large number of specialised equipment and coatings to optimise filtration results and service life:
- Oleophobic/hydrophobic
- Siliconised
- PTFE single-fibre impregnation or coating
- Conductive (anti-static)
- Spark-resistant
- Flame-retardant
- Micro-fibres
- Asymmetrically-designed customised products
- ePTFE membranes
- Hybrid filter materials
- Micro-porous foam coatings
- Nano-coatings
- and more
Antistatic filter media
- For use in potentially explosive atmospheres
- Tested to DIN 54 345 Parts 1 and 5
Needle felts and textiles for the food and beverage industry
Needle felts and textiles used for the filtration of foodstuffs must meet special requirements. In addition to optimum filtration and cleaning properties, their food- safety also plays a decisive role. For these demanding applications we provide a range of certified filter media – with and without ePTFE-Membrane – including a compliance statement to Commission Regulation No. 10/2011 EC and/or compliance with Federal Regulation FDA 21 CFR.
