Frequently Asked Questions

Which fluid dispenser is best for automotive shops?

You'll love how this air-operated system eliminates manual pumping while providing complete mobility around your shop. Unlike gravity-fed dispensers that require elevated positioning, this pressurized system delivers consistent flow at any height and location.

How does this compare to hand pump fluid dispensers?

This air-operated dispenser offers significant advantages over hand pump models. While manual dispensers require constant pumping effort and can cause fatigue during large jobs, this system uses shop air for effortless operation. Once pressurized, you get continuous dispensing without physical effort.

What types of fluids can I use with this dispenser?

This dispenser works perfectly with motor oil, synthetic oil, ATF (automatic transmission fluid), gear oil, and other light automotive fluids. The steel construction and proper sealing make it suitable for petroleum-based fluids commonly used in automotive service.

Do I need to keep it connected to air pressure while dispensing?

No, that's the beauty of this pressurized system. Simply connect shop air to charge the tank, then disconnect and roll it wherever you need to dispense. The internal pressure maintains dispensing capability without continuous air supply, giving you complete mobility around your workspace.

How do I know when the tank needs refilling?

The built-in sight tube lets you see the fluid level at a glance, so you always know how much fluid remains. This eliminates guesswork and prevents running empty during important jobs.
