INTRODUCTION
The AirWall dust scrubber is a stand-alone unit that may be installed in an existing
location or as part of a new piece of equipment. Capacities range from 10,000 to
30,000 cfm per unit for standard modules. Custom configurations can provide filtration
capacities over 100,000 CFM. Standard Specifications are listed at the end of this
chapter.
Because of the cfm capacity range, the AirWall Scrubber units can be configured to
meet required linear air flows for practically any equipment or space ventilating
requirement
SYSTEM DESCRIPTION
The AirWall Scrubber is designed with large inlet and outlet plenums, resulting in low
static pressure requirements. This allows the use of relatively low horsepower motors
and low decibel level blowers. This results in cost efficient ventilation of large, dusty
environments found in tunneling and mining operations. Incoming air passes through
the protective baffles on the front inlet where large or heavy particles are stopped to
prevent filter damage. The dust-laden air then passes through the filter medium from
the outside to the inside of the filter cartridges and out the open top of each cartridge.
This leaves the dust on the out-side surface of the cartridges. The filtered air then flows
from the cartridges into the clean-air plenum above the filter cartridges where it is pulled
out of the unit to the fan.
Options for the AirWall dust collection unit include:
1.
Time delayed cleaning feature to provide automatic reverse pulsejet
cleaning of filter cartridges during non-working hours.
2.
Integrated control panel including disconnect, motor starter(s), control
transformer, Photohelic gage and switch, and indicator lights. Up to four
(4) AirWall Scrubbers may be controlled from the central control panel.
3.
Hoppers for use with screw or a pneumatic conveying duct to transfer dust
to a central collection point.
4.
HEPA (High Efficiency Particulate Air) filter package.
Each AirWall Scrubber can provide filtration for a variety of dust or other airborne
contaminates, removing sub-micron particles at a high efficiency rate. This allows the
exhaust air to be redirected back into the workplace for exhausting though the standard
ventilation system without contamination of surrounding areas.
