Specifications Details

Designed as an exhausting vertical laminar airflow clean workstation, it is to be used when toxic odors & fumes are present. Intake air passes through a HEPA filter (99.99% efficient on .3 microns) providing a Class 100 airflow into the work chamber, and downward through the perforated work surface. It is then exhausted through the internal wall duct for discharge at the top of the unit. A remote exhaust air system is required to balance the work chamber's airflow pattern. The use of polypropylene offers immunity to corrosion, resistance to acids and solvents, non-conductive properties, and a minimum of maintenance. Unit is complete with storage space. Individually tested & certified to meet or exceed the specifications for Laminar F Flow Clean Air devices as per institute of Environmental Science - IES-RP-CC-002-86.

SPECIFICATIONS

Filter : Three inch HEPA (High Efficiency Particulate Air) type, aerosol challenged, zero probed. Aluminum frame mini-pleat design. Minimum efficiency of 99.99% at .3 microns.

Prefilter :  1" bonded polyfiber media minimizes surface-loading.  78% arrestance ---- 56-57 ASHRAE.

Airflow : Requires facility exhaust. Average measured clean air velocity 90 fpm (+/-20 uniformity. Negative resistance, .50 IWG

Construction : 1/2" white stress relieved polypropylene. Heat welded support seams for additional strength. Work surface perforated front and rear for laminar flow, removable for cleaning. Front loaded HEPA filter. Hinged acrylic face shield. Vented storage cabinet. Support ribs under work surface. Fabricated with all plumbing, instrumentation and electrical complete (as per option requested).

Electrical & Power Requirements : All electrical components are UL Approved. Standard 115V, 15A 1 Ph, 60 Hz.

Motor/Blower Assembly : High efficiency motors to reduce electrical load. Motors are thermally protected & self-lubricating. High capacity metal forward curved blowers with direct drive motors.
