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.
