New abrasive umbrella kits for portable blasters offer protection from overhead feeding systems and from weight-related pop-up failures, according to Pirate Brand and manufacturer Forecast Sales Inc.

Umbrella kits for portable blasters keep the weight of overhead media off the pop-up, the company says.

The umbrellas were previously available only with the purchase of a stationary blast pot.

How It Works

When feeding a blast pot from an overhead hopper, extra weight sits on the pop-up and causes abrasive to embed there and in the o-ring until it doesn't seal properly. Air can then leak around the pop-up, causing an imbalance in pressure above and below the metering valve, eventually destroying both the pop-up and valve, the company explains.

The abrasive umbrella is installed over the pop-up and keeps the weight of the overhead media from sitting directly on the pop-up and interfering with its operation.

The umbrellas come in 18- and 24-inch set-in kits, which are just placed in the bowl of the pressure vessel, and weld-in kits, which are welded to the bowl of the pressurve vessel.
