Product Description


The RESPA®-CF2 is the most advanced Cab Air Quality System available, delivering a powered precleaner, filter, and pressurizer in one compact, customizable unit. This innovation from Sy-Klone International offers the highest quality of filtration and pressurization at the lowest costs.

Self-Cleaning Filter Housing in Action

Sy-Klone's amazing MERV 16 filter and filter housing are incorporated into the RESPA Fresh Air Precleaner/Filter/Pressurizer. This Demo show the self cleaning filter and filter housing in action! The Dozer, running in a coal mine, went from 1.5 days of fresh air filter life on the cab to 1000 hours. Previously the cab would not hold pressure. With RESPA installed, it never loses pressurization between planned maintenance intervals. The high efficiency fresh air filter removes particulate at over 99% down to 0.3 microns and with the optional HEPA filter at 99.75% to 0.3 microns first pass.
