Specifications
General
Furnish one (1) Gaylord ClearAir Pollution Control Unit model RSPC-ESP series as manufactured by Gaylord
Industries of Tualatin, Oregon in accordance with the following:
The pollution control unit shall consist of a smoke control section, odor control section (optional) and an exhaust
fan section (optional) all built on a common base as an integral unit.
Smoke Control Section
The smoke control section shall contain one or more electrostatic precipitator (ESP) Cells to remove
smoke particles from the air stream to a level no higher than 20% opacity when operated in accordance
with the operation and maintenance guidelines. The ESP Cells shall be of a floating plate design to
eliminate plate warpage during high heat operation. The Cells shall be positioned on slide tracks so that they
may be easily removed through a hinged Cell access door(s). For ease of handling, individual Cells shall
weigh less than 54 lbs. There shall be removable, cleanable debris screens located immediately upstream of
the ESP Cells and a moisture separator immediately downstream. An electrical panel mounted on the unit
shall contain the high voltage power pack assembly, safety disconnect switch, main disconnect switch,
fuses and a magnetic starter for the exhaust fan when fan is included. The safety disconnect switch shall
interface with the electrical panel access door such that when opened it will shut off service to the power
pack(s) and ground them to drain the residual electrical charge from both the power pack(s) and ESP Cells.
The ESP Cell access door shall interface with the electrical panel access door so that it cannot be opened
without first opening the electrical panel access door. The high volt- age power pack(s) shall be self-
limiting type and shall be self-contained. The electrical panel shall include indicating lights to monitor Cell
and transformer voltage. The main disconnect switch for the exhaust fan and control circuits shall lock
the electrical panel access door closed when in the “on” position. The unit shall contain one or more wash
manifold(s) with brass spray nozzles to wash the ESP Cells with hot detergent injected water each time the
exhaust fan is shut off.
Fire Detection
A thermostat, set at 250o F, shall also be located in the filter section to shut down the exhaust fan in the
event of a fire.
Optional Fire Damper for use in Canada
___The unit shall include a UL listed fire damper, with a 280o F fusible link, located downstream of the
filters to prevent passage of fire to the duct downstream of the unit
Odor Control Options
___Media bed of 50/50 Blend Potassium Permanganate and Carbon Blend
The unit shall be provided with odor control utilizing a media bed of 50% potassium permanganate 50%
carbon blend. There are two design methods of housing the media used in the ClearAir unit. One is called
the Loose Fill type and the other is called the Media Panel type.
___Loose Fill type – The odor control media shall be housed
in steel reusable Media Modules that can be
replenished
with Loose Fill media. There shall be a 30% pleated media After Filter located immediately
downstream of the Media Models.
