Full blast gates (also called cut-offs) are used to open and close branch ducts in a system allowing air to be diverted only to machines that are operating, thus conserving air volume. Sliding galvanized blade features a locking screw for full volume control including balancing.

Self-cleaning gates are the same construction as our full blast gates except the galvanized steel slide moves through the open end to push out debris from wood pulp and sticky materials.

C.R.S. steel blast gates are constructed the same as our stainless steel gates. These gates are more economical than stainless steel when elevated temperature or corrosion resistance is not required.

Our air-operated gates are fully automatic using an air cylinder that has power in both directions. Instant open/close. 35 lb. load capacity at 80/90 psi., ¼ in. NPT ports. No lubrication required, air cylinder is standard.

These fabricated gates use the same air cylinder and mounting as the cast aluminum, except the gate is all steel or stainless steel for use in high temperature, food or corrorsive applications.

Electric operated gates use a powerful 12 volt DC motor rated at 5 AMPs. Open/close speed of 2 inches per second. Use of a 10 AMP power transformer is required (able to operate two motors) and reversing switch to operate.

Positive seal, also called "vapor proof" gates, are used in applications that require no external air leakage. Internal leakage is minimal. Not recommended when material is in the air stream. Galvanized steel body is standard, stainless steel is optional.
