ASME-Code Compressed Air Storage Tanks


Horizontal	Horizontal with Mounting Plate

Vertical

These tanks have drain ports on the bottom to remove condensation. All other ports can be used as inlets or outlets in any configuration.

Steel tanks are primed or powder coated for exterior corrosion resistance.

Note: Per ASME code, all tanks are water tested. Those made without a corrosion-resistant coating or material will have rust on the interior.

With Mounting Plate—Tanks with mounting plate have a platform where you can secure motors, pumps, and other components.

Epoxy Liner—Epoxy-lined steel tanks also resist interior corrosion that can result from moisture in your compressed air.

Hydraulic Tanks

Style C

Store fluids for a hydraulic power unit or circulating-oil system. Choose a tank capacity about three times greater than your requirement to allow for heat dissipation. Tanks with only a drain connection require you to drill your own inlet/outlet connection and add pipe suction flanges (sold separately). Flanges seal pipes that pass through the top plate of your tank.

Dual Chamber Tanks—Dual chamber tanks have a divider that allows particles to settle on one side before fluid is returned to your line.

Style C—To install the breather vent to Style C tanks, drill a hole in the tank.

Double-Wall Plastic Tanks


	Shown Separated

No need for separate spill-control pallets or trays—comply with EPA regulations for storing hazardous liquids with just one tank. These tanks have two walls, so if the primary compartment ruptures, the secondary one will contain the leak. It can hold 110% of the primary tank's volume and will also protect it from damage in case of impact.

Made of polyethylene, these tanks can store a broader range of chemicals than steel double-wall tanks. The plastic contains UV inhibitors so they can be used outside.

These tanks have a flat space on top where you can mount a metering pump.

NSF/ANSI 61—Because these tanks meet NSF/ANSI 61 for drinking water, you can meter chemicals stored in them into your drinking water system.
