DETAILS & SPECIFICATIONS
FOR APT INDUSTRIES' AIR WASHER COMPONENTS

AIR WASHER
The APT Air Washer is a highly efficient conventional velocity air washer. The standard spray water density of 8.5 GPM per 1000 CFM of air produces a saturation efficiency of 95% at the standard face velocity of 550 FPM. The standard design utilizes a double bank of opposed sprays with vertical 3 bend inlet baffle blades and vertical 6 bend moisture eliminator blades, all housed in a 8'-0" long casing. Special designs are available, utilizing from one to four banks of sprays. Medium & High velocity designs are also available, allowing face velocities up to 1300 FPM.

AIR WASHER TANK
The tank provides the foundation for all the air washer components. It is constructed of seam welded 12 ga. stainless steel. The standard tank is 18" to 24" deep and is provided with a flat bottom.
Tanks may be provided in other materials such as galvanized or hot rolled steel up to 3/16" thick. Extensions of varying lengths are offered for independently removable double suction screens, weirs, special overflows or chilled water connections. Tank sides are insulated with metal skinned foam insulation. Washers may be provided for installation on a concrete tank provided by the owner.



AIR WASHER CASING
The casing is mounted with gaskets onto the air washer tank and forms the spray chamber. It is constructed of double wall APT-O-LITE™ foam insulated panels with any combination of aluminum, galvanized steel or stainless steel skins. A large marine type inspection door facilitates examination of the sprays and maintenance.
The casing may also be constructed of angle reinforced single wall galvanized or stainless steel. Interior marine lights are available.


MIST ELIMINATOR AND INLET BAFFLE BLADES
Eliminators are located on the air-leaving end of the washer to remove entrained water droplets from the air. The eliminator blades are of the 6 bend design and are spaced on 1 1/8" centers extending from below the water level of the tank to the top of the washer. The blades are formed from 26 ga. stainless steel with interlocking stainless steel retainer spacers.
Eliminators are also available in 26 ga. galvanized steel. Blades may be individually hinged to ease cleaning and removal.

Inlet baffles are located on the air-entering end of the washer to insure uniform air distribution through the spray chamber. The baffle blades are of the 3 bend design and are spaced on 3 3/8" centers extending from below the water level to the top of the washer. The blades are formed from 26 ga. stainless steel with interlocking stainless steel retainer spacers.
Inlet baffles are also available in 26 ga. galvanized steel and may be individually hinged to ease cleaning and removal.


SPRAY PIPING
The two opposed banks of sprays consist of an assembly of headers, standpipes, nipples, and spray nozzles all drilled, tapped, and threaded to simplify installation and removal. The headers are fabricated from schedule 40 galvanized pipe and provided with a corrosion resistant coating.

The standpipes are also fabricated from schedule 40 galvanized pipe as well as the nipples. The spray nozzles are a two piece design, brass centrifugal type with a large diameter body inlet and removable cap orifice for non-clogging free flow. A slotted suction pipe is provided to prevent pump cavitation. The suction pipe is fabricated from Schedule 10-Stainless Steel.

The overflow and drain are also fabricated from Stainless Steel Pipe. The make-up includes a 1" quick-fill, a hose connection and CLA-VAL float valve to set the water level.

Alternate materials such as stainless steel, galvanized steel, or PVC may be provided for any or all of the piping components. Alternate spray nozzle designs and materials are available. Flooding headers and nozzles to aid cleaning the eliminators and baffles are also available.
