MANUAL BLAST GATES
Cast Aluminum Full Blast Gate|
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.Prices & Sizes .pdf Spec Sheet
|Cast Aluminum Half Blast Gate|
Half blast gates are used when adding a gate to an existing branch duct that is prone to clogging or a very abrasive material as this gate adds no internal obstructions. Galvanized steel slide with locking screw.Prices & Sizes .pdf Spec Sheet
|Cast Aluminum Self-Cleaning Blast Gate|
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.Prices & Sizes .pdf Spec Sheet
|Stainless Steel Fabricated Blast Gates|
Stainless steel fabricated gates are constructed from 12 ga. 304 stainless steel body and slide blade. Bolt together body allows dissassembly for cleaning. Welded collars are standard, angle ring flanges are available. 316 stainless steel is also available at additional cost (see .pdf Spec Sheet for pricing).Prices & Sizes .pdf Spec Sheet
|Galvanized Steel Fabricated Blast Gates|
Galvanized 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.Prices & Sizes .pdf Spec Sheet
AUTOMATIC BLAST GATES
|Pneumatic Cast Aluminum Full Blast Gates|
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., 1/4 in. NPT ports. No lubrication required air cylinder is standard.Prices & Sizes .pdf Spec Sheet 2-7" .pdf Spec Sheet 8-24"
|Pneumatic All Galvanized or Stainless Steel Blast Gates|
These fabricated gates use the same air cylinder and mounting as the cast aluminum, except the gate is all galvanized or stainless steel for high temperature food or corrosive application.Prices & Sizes .pdf Spec Sheet 2-7" .pdf Spec Sheet 8-24"
POSITIVE SEAL "Vapor Proof" BLAST GATE
|Positive Seal "Vapor Proof" Fabricated Blast Gate|
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 at additional cost.Prices & Sizes .pdf Spec Sheet
