  • Door-to-door removal of harmful emissions
  • Speed-absorbing shock system
  • Front and rear door release
  • Expandable design
  • Accommodates up to four vehicles in tandem
  • Adjustable release points depending on speed of all-out release

Fully automatic

The system is fully automatic, from the fan activation to the automatic release from the exiting vehicle. There is a one-step connection to the system as the vehicle enters a garage.

The STR is the right choice if you want an exhaust removal system that is easy to use and ensures effective and efficient diesel exhaust gas removal for multiple vehicles in line.

Fire truck up to 16 ltr engine:
630 cfm (1070 m3/h)
Fire truck up to 24 ltr engine:
1060 cfm (1800 m3/h)

Recommended Air Velocity

In ducting:
2000 - 3000 fpm (10 - 15 m/s)


Internal Trolley
The unique internal crab trolley travels inside the STR rail profile and pulls open the sealing lips as it moves.
The non-locking spring recoil balancer controls the point at which the Grabber disconnects from the tailpipe. As the hose reaches its maximum length, the balancer locking cable will bottom out, in turn pulling the nozzle from the moving vehicle.
Hose Package
The hose package consists of the following:
• upper hose and metal saddle
• mid-hose
• lower hose with Safety Disconnect Handle and either Magnetic or Pneumatic Grabber® nozzle, based on operator preference and station design.
Hose Length:
Lengths are available in 19.7 to 32.8 ft (6 to 10 m)
Hose Diameter:
Diameters range from 4 to 6 in. (100 to 160 mm)
Safety Disconnect Handle:
Provides large grips so that it can be operated even while wearing gloves and can be reached from any angle.
Mounting Kit & Suspension Bracket:
Adjustable for angled ceilings to adjust the pitch to vertical. The horizontal slide plate allows adjustment away from or closer to the wall.


Tailpipe Reducer & Bracket
The tailpipe reducer easily converts an exhaust tailpipe to a larger size so that the conical tailpipe adapter can be installed. In addition, a tailpipe support bracket ensures a secure connection between the tailpipe and body / chassis.
PC-500 Pressure Sensor:
Pressure sensor for automatic exhaust fan start.
See separate data sheets for F-Series and TEV fans and mounting kits.
Starter SA-24 or OS-3:
Automatic control unit for exhaust fan, which can be controlled by a manual or automatic pressure sensors.
