Preval Sprayer Replacement Power Unit #268

A fresh charge for the Preval system. The power unit is the aerosol engine that drives the sprayer: 1.94 oz (55 g) of propellant that atomizes up to 16 oz of liquid, up to 18 minutes of total spray time. Screw it onto any Preval jar or reservoir and you are back in business.

Because the venturi design never mixes propellant with your coating, a spent power unit is the only thing you replace. The glass jar, cap, and dip tube in your complete spray system keep working for years. Keep a spare or two in the drawer so a dead can does not stall a gelcoat repair mid job.

Specs

Contains a pressurized flammable power unit, so it ships ground only (lower 48). California Proposition 65 warning applies; see P65Warnings.ca.gov.

Pairs with the Preval complete spray system and styrene thinner for gelcoat work.
