Step 1. Funnel Gasket Installation

Place funnel assembly upside down on a table or bench. Peel off paper backing from 1" wide foam gasket and apply to lip of funnel. Trim length of gasket as needed. Use a punch or nail to make holes in funnel gasket for bolt installation.

Step 2. Leg Installation

Place cabinet on its back on a table or bench. Remove (16) 1/4" x 20 x 1/2"L bolts and locking hex nuts from bolt packet. Insert 1/4" bolt through leg and into cabinet. Place 1/4" locking hex nut over bolt and hand tighten. Repeat above for remaining three legs.

Step 3. Funnel Installation

Stand cabinet upright. For easier installation, remove screws from black glove flanges and pull out flanges with gloves from cabinet body. With gloves and flanges removed, there will be extra room for funnel to be inserted into cabinet body.

Insert funnel assembly through bottom of cabinet. This will require holding funnel at a slight angle until once inside bottom lip of cabinet. Once funnel is installed, reinstall glove flanges to cabinet.


Remove four 1/4" x 20 x 1"L bolts, and four locking hex nuts from bolt package. Insert four 1/4" bolts though holes in funnel (inside cabinet). Place locking hex nuts over bolts and hand tighten. Tighten leg bolts and level cabinet.

Step 4. Hose Installation

Insert end of blue 7' whip hose through cabinet grommet on front of cabinet. Connect to bottom handle of S-25 power gun by screwing into place (use Teflon tape or pipe compound - DO NOT OVER TIGHTEN). Connect clear siphon hose from pickup tube in funnel to power gun (slip fit). Connect your air hose to other end of the 7' air hose.

Step 5. Vac Ferrule Installation

Remove four screws installed on the left side of the cabinet. Attach vac ferrule to cabinet by inserting sheet metal screws through vac ferrule and gasket. Tighten screws securely to compress gasket. Your shop vacuum will connect to this ferrule to remove dust created in blasting.

When using a shop vacuum, be sure to install the paper filter over the standard filter. Otherwise, abrasive could work its way into the vacuum motor, causing bearing failure. Glastar sells a preliminary filter, which can be placed over the conventional filters used in most shop vacuums. This filter bag is constructed of a special "soil release" material, which will be easy to clean and will help prevent dust and abrasive from passing through the conventional filters included with most shop vacuums.

Step 6. Load Abrasive

Add 15-20 lbs of suitable abrasive by pouring through top-loading door opening into funnel hopper. NOTE: always use a fine grade of abrasive to prevent clogging

We recommend straining through a double layer of ordinary window screen or our Abrasive Sifter. If it passes though the screen, it will pass through the nozzle.

DO NOT OVERFILL FUNNEL - Fill only about 1/3 of the hopper (in most cases, this is about 15-20 lbs of abrasive). Too much abrasive will pack and not feed properly

General Operation Instructions

Place piece to be blasted on the work area screen inside cabinet

Close & latch loading door

With hands in cabinet gloves, hold piece with left hand and hold blasting gun with right hand (if you are left handed, hold gun in left hand and piece in right hand)

Aim at a slight angle to the work being blasted and pull trigger of blasting gun.

Abrasive will come out under pressure

Abrasive will drop to the bottom of the funnel for recycling

Dust is drawn into the vacuum system from the left side, providing good visibility within the cabinet.

Abrasive should be changed then it gets "dusty" and visibility is poor.

Abrasive will eventually lose its sharpness after it breaks down, so change on a regular basis. When the abrasive breaks down to this "dusty" consistency, it can clog your shop vac filter and result in poor vacuum suction. However, no matter how careful you are, some dust and abrasive will always be in the area of the cabinet. For this reason, we do not recommend locating the cabinet in the vicinity of an air compressor or other equipment that should be in a clean atmosphere.

To change the abrasive, place a container under bottom of funnel and open spring-loaded trap door, allowing worn abrasive to drop into container. close trap door and refill with new abrasive or recycle your old abrasive.
