Saddle Vent

The Saddle Vent® History
The Saddle Vent® was invented and developed by Air Systems and has been used around the world for over 20 years to make it easier and safer for workers to enter and exit a confined space. The Saddle Vent® takes up only 3 inches in a manhole opening and functions as a fresh air conduit to the workers in the confined space. With the Saddle Vent® in place, continuous ventilation is supplied to the workers by eliminating the need to remove the air duct each time a worker needs to enter or exit a confined space.

In-Line Axial Fans

The 10" in-line axial fan has been designed to be used as a stand alone fan or it can be attached in series to run long lengths of ventilation duct. Intake and exhaust flanges allow for either 8" or 10" duct to be attached to either end of the blower to achieve positive or negative ventilation. The blower is light weight and weighs less than thirty pounds; it is available in standard electric or explosion-proof electric.

The Latest Innovation in Saddle Vent® Technology

Conductive Saddle Vent

The Conductive Saddle Vent® System is now standard with our explosion-proof & pneumatic blower kits or it can be purchased separately to upgrade your current ventilation procedures.

Saddle Vent® Safety Improvements

The original Saddle Vent® was constructed of standard polyethylene which carries the potential of static electricity build-up on its surface. Static electricity is a source of ignition for fire and explosions.

Air Systems developed an improved Saddle Vent® to safely remove potential static electricity charges from the ventilation system. The use of conductive polyethylene to construct the Saddle Vent® and conductive ventilation duct now provides the safest possible confined space ventilation procedure available.

The fully Conductive Saddle Vent® removes static electricity from the entire ventilation system when installed properly.

The Conductive Saddle Vent®

System Set Up Procedure

Step1) Select an electric explosion-proof or pneumatic blower with an installed metal grounding lug.

Step 2) Read and follow recommended work procedures found in ANSI/API 2015 and 2016 prior to entering a tank or confined space.

Step 3) Use only conductive ducting supplied with a continuous metal helix and a static ground wire connected to the helix. The ground wire is connected to the metal ground lug on the blower. (See Pic. 1)

Step 4) Attach the conductive elbow to the top of the black Conductive Saddle Vent®, (see Pic. 2), and attach the ground wire from the duct to the elbow. If no elbow is used, an alternate ground lug is provided on the top of the Saddle Vent®.

Step 5) Attach conductive duct to the base of the Saddle Vent® and attach the ground wire to the Saddle Vent®.

Step 6) Test the ventilation set-up for conductivity prior to starting ventilation. Use a volt/ohm meter set to read ohms in "thousands". Attach a lead from the meter to the farthest end of the duct's grounding wire and the other lead touching the ground lug on the blower. A reading less than 500 K ohms will assure a good ground is achieved to allow any static charges to flow toward the grounded source (See Pic. 3). Pneumatic blowers should have a ground wire run from the blower to a grounded source.

Step 7) The ventilation system is now ready for use. Place the duct and Saddle Vent® system in the manhole and secure with the universal mount. Follow the "Typical Saddle Vent® set-up" procedure found in your blower's instruction manual.
