Custom Designed Exhaust Systems
The Harvey model #TS-30 is “TELESCOPICALLY®" designed to simplify and improve upon existing overhead exhaust drops currently available. The #TS-30 consists of three lengths of lightweight, flexible tubing that slide one into another and give the appearance of only one 6' length of tubing attached to the overhead duct.
The tubing and tailpipe adapter that connect to the vehicle are non-crush, neoprene rubber. Drive over it! The tubing and adapter cannot be crushed or damaged. Pull-up sets are not required with the #TS-30 and #TS-40 drops.
The HRX-812's elliptically shaped aluminum rail allows for efficient airflow and sleek styling. The easy-glide trolley assembly allows drops to be shared among bays (check state and local codes). It also features pinned joints to guarantee easy alignment of rail sections and our “Positive Pull" nut and bolt joining system with gasketed seams to ensure a simple, trouble-free installation.
Trolley assembly can be fitted with the standard #TS-30 drop or the #3-Skyhook balancing pull-up configuration or any of the RHR series hose reels. The heavy duty trolley assembly is fitted with eight ball bearing wheels for smooth operation.
Rail systems also available for heavy duty transit truck/bus or industrial applications.
An overhead system is easily installed in an existing or new building. A single drop is normally located at the side of the stall approximately 1' behind the rear vehicle bumper. The ductwork should be at an elevation of 15' to 16' A.F.F., which would then allow the standard 20' hose drop to attach to either right or left side mounted tailpipes.
An overhead drop is installed by slipping the overhead coupler over the appropriate size stub or airflow “T" of the ductwork. The overhead coupler is held in place with a bolt through the assembly.
For dual exhaust vehicles, a “Y" harness should be used in conjunction with the overhead drop.
Various types of pull-up sets are available to retract hose drops when not in use, such as Harvey's No. 1, 2, 3, or 4 Skyhooks.

The body of the PS Floor Fitting is plastic molded from high-temperature resistant polyethylene. The top flange and lid of the PS Fitting is cast aluminum with the 5/16" thick lid having a tensile strength of 35,000 pounds. The lid is attached to the flange with a heavy-gauge, all stainless steel piano hinge for easy maintenance.
When in the open position, the lid rests solidly on the floor. The molded plastic Floor Fitting offers reduced costs and is impervious to all the elements for years of trouble-free service. The base is designed to fit the Harvey Molded Plastic Pipe Saddle, which allows for approximately 4" height adjustment.

Direct drive, BD-7 and BD-8 belt drive blowers are either forward curve or radial blade. All other belt drive blowers are backward curve. All blowers comply with AMCA Standard 210 and bear the AMCA Seal.
Various types of installations may require accessories for the blower such as:
All-Weather Cover
Back Draft Damper
Vibration Pads
Belt Guard
Acid-Resistant Coating of Air Stream
Spark-proof Construction

AR Series Rubber Stack/Tailpipe Adapter
A-Smooth bore mounting base for use with smooth bore hose.
FMETG
For use on vehicles with flush mount or recessed tailpipes. The wire form is installed in the tailpipe adapter and the flexible metal bar is inserted into the tailpipe to hold the hose and tailpipe adapter in place.
Stainless Steel Tapered Adapter With Spring Closing Cover
Specifically for rubber, silicone fiberglass, or metal tubing.
Hose Couplers
Cast aluminum hose coupler used to connect various lengths of rubber hose when “Twist Lock" feature not available.
Hose Guides
Standard with all Harvey underground units. The hose guide serves two purposes: to guide the rubber hose easily through the underground system and to prevent rags, etc. from being sucked into the system. Also available for metal tubing.

Old style floor fitting, replacement units available.
Cast Aluminum “Y" Fittings
For use in “Y" harnesses.
Energy Saving Dampers
Mounted in the hose drop of an overhead system to cut off the majority of air flow when not in use.
Elbow for Lifting Overhead Drops
Cast aluminum elbow joins two hose lengths and eliminates kinking of hose when pulled up out of the way. Used in place of damper.
Overhead Duct Couplers
Harvey Overhead Duct Couplers simplify installation of overhead rubber drops. One end of the cast aluminum coupler threads into the rubber hose and the other end slips over stub of the duct work. A bolt through the assembly completes installation of the overhead drop.
