What size vehicle do I need for a skid sprayer?

UTV skids (60–100 gal) fit most utility vehicles. A 200-gal fire skid suits a ½–¾ ton truck; 300–500 gal models need a 1-ton or larger. Confirm filled weight (water ≈ 8.34 lb/gal).

What’s the difference between diaphragm and centrifugal pumps?

Diaphragm pumps provide higher pressure for long-range spot spraying and tree work; centrifugal pumps provide higher flow for dust control, quick fill, and fire streams.

Can I mix fire retardant?

Yes, fire control skids are compatible with approved retardants. Follow chemical guidelines and flush after use.

Are units shipped assembled?

Yes. Units arrive skid-mounted and ready to use after basic setup.

Marine Holding Tanks

Our marine holding tanks are extremely strong and sturdy. They are manufactured using rotomold technology, which means that this marine waste holding tank has 3/8” thick walls and is nearly unbreakable. It has no seams, which means there’s less opportunity to break or leak. Fittings are spin-welded to ensure secure, leak-proof connections. These marine black water holding tanks comply with FDA and Coast Guard standards. Simply indicate on the tank drawing where you’d like your fittings placed!
