Sy-Klone's RESPA-SD is a powered precleaner, filter and pressurizer. This one piece unit provides high efficiency powered precleaning using Sy-Klone's patented Gideon Technology coupled with a fully integrated sealed filter housing. Filtration options range from MERV 8 to HEPA. The Gideon Powered Precleaner, which is integrated into the RESPA-SD, is responsible for removing up to 96% of the debris prior to the air passing to the filter housing. Filter life extension is up to 30 times more than traditional HVAC fresh air filter systems. This low cost, low weight fully engineered product is the most technologically advanced HVAC fresh air system available today. It adds additional benefits such as keeping the evaporator coils clean, extending HVAC service intervals and it provides extremely clean air up to HEPA level to the operator cab.
