Downdraft Diffusion Media

PA 560 G-10

PA/560 G-10 micron is a progressively structured diffusion media created by Viledon® to optimize laminar air flow. Manufactured from thermally bonded synthetic fibers, Viledon’s diffusion media has set the standard in paint booth filtration world wide.


R1 media is designed by Viledon®  for equipment protection or for general filtration requirements. The progressively structured single ply media is thermally bonded and treated with a special adhesive tackifier.


Pro-Tech Gold

The Pro-Tech Gold filter is designed for use in all types of HVAC systems and cross flow paint booth applications. It provides significantly reduced maintenance costs, high efficiency air filtration and outstanding filter to filter and perimeter sealing integrity.  Pro-Tech Gold Panels and links have a unique design that creates strong perimeter seal between filters and filter banks alike. Replacement is faster and easier than products which utilize hooks, clips or tool requirements. Pro-Tech Gold Panels & Links are ideal for light-medium crossflow overspray booths.

High Temperature

AmAir HT

The AmAir HT pleated filter is designed for conditions that require a U.L. Class 1 filter and for applications with continuous operating temperatures of up to 500˚F. AmAir HT is made with ultra-fine glass fibers formed into a high loft mat, increasing its dust-holding capacity. The frame is an aluminized steel U-channel, with the scrim-backed media pack bonded to the inside on all four edges. An expanded aluminized steel faceguard is spot welded inside the frame on the air leaving side to retain the media pack at elevated temperatures.

VariCel HT

Designed for systems operating from 350°-900°F, VariCel HT filters feature aluminized steel construction. They are widely used in automotive paint drying ovens to filter recirculated air. Available in 90-90% and 60-65% efficiencies.

Evaporative Cooling Media

Munters CELdek

Munters CELdek is a high efficiency evaporative cooling media that is engineered to provide maximum cooling and humidification, low pressure drop and years of reliable service.

Columbus evaporative cooling

Since the 1970’s, Columbus Industries has manufactured effective, efficient and long-lasting evaporative cooling pads.

In many regions of the world, evaporative cooling is the most effective means of air conditioning. Columbus Industries designs, manufactures and distributes cooling pads for residential, commercial and industrial applications.



Specifically designed for quick maintenance change outs, the Velum filter enables protection of air intakes for sensitive equipment which otherwise would be defenseless against indoor particulate. The unique roll design which offers full protection of motors, electronic components, cooling systems, while simplifying installation and filter advancement.


TSI VelociCalc 9555

The VelociCalc 9555 Multi-Function Ventilation Meter is a portable, hand held ventilation test instrument. This instrument is designed to work with a wide range of plug-in probes. The probes allow users to make various measurements by simply plugging in a different probe that has the features and functions best suited for a particular application. With the optional probes, measurements include air velocity, temperature, humidity, pressure, CO and CO2. Calculations include air flow, heat flow, turbulence, wet bulb and dew point temperature.

“I” Connector

I Connectors are constructed of a combination of recycled and virgin grade rigid P.V.C. Plastic. I Connectors are used to connect 2″ filter panels in a side access filter bank. Bypass is prevented and the structural integrity of the filterbank is improved. “I” Connectors may also be used as spacers at one or both ends of the filter track to prevent bypass between filter panels and wall sides.
