The MacBone P150 air filter and cab pressurizer assembly is designed to bolt directly to either of the long sides of any MacBone rooftop unit. This assembly provides filtered outside air, under pressure, of up to 30% of system circulated air, thus providing filtration with a high level of cab pressurization. The MacBone "-6" models have all the bolt holes and plug-in wiring to accommodate the P150; the "-5" and earlier models require mounting holes to be drilled. The electrical requirement for the P150 blower is 12 or 24 volts D.C. at 6.5 amps. The filter element supplied with the P150 is a Donaldson "Vacu/Safety Filter", model G070017, and is available from us or from any Donaldson distributor. For MacBone units ordered with the P150, we will be happy to preinstall it as a courtesy.
