Gate Systems 13×42 Low Profile (A87)

air brake company Gate-Systems 13×42 Low Profile (A87)

The A87 low profile outlet gate is commonly referred to in the industry as a 13” x 42” sand gate.  With an opening size of 21” x 54” this gate is available in either 32 or 64 bolt hole pattern designs.  Along with the standard AEROgate features, an under door seal is applied to this gate in order to prevent “back puffing” when unloading.  Additional options are available.
This gate was originally designed as a low profile gate for some sand applications.  Its low profile design allows for lateral conveyor unloaded at remote facilities.  We would also recommend the A161 for these low profile sand and frac sand applications.
