Description
FEATURES:
- Power module includes a 3/4 HP motor with direct-drive cast-aluminum blower. The motor/blower is mounted to a stainless-steel base with attached manual starter (with thermal overload protection), Start/Stop toggle switch, and hard-wired power cord & plug.
- The blower is rated at 500 CFM @ 2” static pressure water gage (sp.wg.) and 390 CFM @ 4” sp.wg.
- Filter module consists of a portable stainless-steel housing that holds one AK78 HEPA filter and one pre-filter (AK66 MERV-9 3-ply pre-filter or AK93 carbon-impregnated pre-filter or AK67 spark-arresting pre-filter). Additional filter modules (sold separately) can be joined in series to provide a custom inline-filter combination to meet specific end-user application requirements.
- The selected pre-filter is inserted (and removed) via a dedicated access door at the top of the filter module. This allows for quick-and-easy change-outs without disturbing the HEPA filter seal. Pre-filter change-outs can be performed while the vent unit is still running. No need to shut it down.
- The filter module is equipped with an inlet-plenum “Accessory Track” which accepts one of several flex-duct inlet adapters or special attachments. The MAC-21 comes standard with an 8” diameter duct collar (with roll bead) welded to a SS plate secured within the Accessory Track. If desired, the end-user could (for example) replace that 8” dia collar plate with a 6” or a 10” dia collar plate (sold separately). The accessory is also used to connect the MAC-21 to a 55-gallon drum-inspection hood (PN GU11/BC03) or an 85-gallon drum-inspection hood (PN GU12/BC03), both sold separately.
- The quick mount cart functions as the mounting platform and handling device for the Modular Air Cleaning system. Components are constructed from stainless steel tubing resembling a “hand truck” in design.
