|Evaporator coils for a residential air handler (cont.) Uncased, pre-charged with R22 refrigerant, with flanged mounting base plate, connector tubing, refrigerant fill valve and check valve, twin-finned radiator baffles. For use in conjunction with heat pump units, to be mounted indoors in air handler or air handler ductwork; cased units are to be used for outdoor mounting. Sized by the associated nominal tonnage of the heat pump. Add for LEED certification if required.|

|Central air particulate removal filter system Residential or light commercial DOP (di-octyl phthalate) type. Provided as drop-in module to manually fit into an air handling units. Complies with Mil-STD 282 (certified removal of 99% of dust particles over .3 microns in size) as well as ASHRAE specifications. For homes, medical clinics and pharmaceutical manufacturing/test facilities. DOP filter type is non-woven denier nylon/cellulose acetate composite with activated carbon final layer. Optional Dwyer-type pressure differential switch and relay provides for automatic shutdown of air handling unit and triggering of signal light when filter elements are clogged with particulates and require cleaning or replacement. Pressure drop across filter is 1" W.C. (water column) to 2" W.C. Sized according to nominal tonnage of associated cooling/heating capacity.|
