Koch 574-020-020 – 20×20 Synthetic Pre-Cut Air Filter Pad, MERV 4 (50 pcs)

Synthetic Air Filter Media:

This broad spectrum of products is designed for use in Koch Pad Frames, and is also available in bulk rolls for customers preferring to cut their own pads. Koch Synthetic Air Filter Media is primarily used as a prefilter for more expensive final filters, often extending the life-cycle of these final filters by 50% or more. Other popular applications include gas turbine air intake systems, commercial/ industrial central air handlers, unit ventilators, fan coil units, or any system where fiberglass or other filtering materials are not preferred.

Type SPT5: A nominal 1/2"(inch) thick airlayed polyester media with a weight of 4 ounces per square yard. The media is white in color with a blue tint on the downstream side. This blue tinted area is treated with a dry tackifier to enhance dust holding capacity. The media is available in pads or 135' bulk rolls. SPT5 is an ideal media for 1"(inch) frame or blanket installations where upgraded dust holding capacity is needed.
