Details

Reducer Coupling available on GW6 models (6" discharge). Reduces discharge to 4" for use with 4" discharge pipe.

Factory Installed Quick Exhaust Valve - GWE models have Global's unique G-Series quick exhaust valve permanently mounted. This patent pending valve was designed specifically for use with Global Air Blasters. It quickly evacuates air from the Air Blaster valve, guaranteeing a full, powerful blast even when the solenoid or 3-way valve is up to 100' from the Air Blaster. The G-Series quick exhaust valve also ensures closure of the Air Blaster valve immediately after the blast. This prevents contamination from entering valve or tank.

Stainless Steel models for use in corrosive or "clean" environments. Includes stainless tank, valve body, cap, and seat, polypropylene piston, Teflon encapsulated or silicon o-rings. No lubrication required.

Special Paint and other modifications to meet individual applications.

Filtered air. No lubrication required.

40-125 PSI.

Maximum Ambient Temperature = 130°F (55°C).

Manual Valves - 2-way manual ball valves, used to control the air supply to the Air Blasters and 3-way manual ball valves for manual firing of the Air Blasters.

Solenoid Valves - 3-way normally open solenoid valves for automated firing of the Air Blasters.

Airline Kits - Recommended for trouble-free operation and long life of Air Blasters. Includes airline filter and pressure regulator with gauge. Either standard or auto-drain models available.

Airline Check Valves - Used to prevent accidental firing of Air Blaster if air supply problem causes pressure to drop in Air Blaster fill line.

Quick Exhaust Valve - This patent pending valve was designed specifically for use with Global Air Blasters. It quickly evacuates air from the Air Blaster valve, guaranteeing a full, powerful blast even when the solenoid or 3-way valve is up to 100' from the Air Blaster. This valve increases the blast force by as much as 20% compared to other quick exhaust valves or a tank mounted solenoid. The G-Series quick exhaust valve also insures closure of the Air Blaster valve immediately after the blast. This prevents contamination from entering valve or tank.

Tangential Mount Discharge Assemblies - Directs air blast downward and along the bin wall. Tangentially directed blast, a process patented by Global Manufacturing, is the most effective way to clear material sticking to the bin walls. Assembly includes mount plate, discharge pipe, mount flange, gasket, and hardware. Available in weld-on and bolt-on versions.

Mount Hardware Kits - Straps and hardware for supporting tanks when bin wall strength is not adequate.

Blaster Master Timer - A micro-controller based sequencing timer used to control the firing time interval and sequence of one or more Air Blasters.

Safety Cable Kits - Includes anchor ring and 14 feet of cable.

Produces Results Quickly and Efficiently - Quick blast of air permeates the material and dislodges trapped solids. Handles Big Loads - Air blast spreads out in a cone pattern to aerate and loosen a large volume of material at one time. When used in combination, multiple Air Blasters can restore flow to hundreds, thousands, or millions of cubic feet of material. Quiet Operation - Noise of air blast is dampened by the material being aerated. Energy Efficient - Air Blasters have low air consumption since they collect air and are fired intermittently. They require only a small fraction of the air used to operate pneumatic vibrators. Does not Compact Material - Blast of air in the bin aerates the material rather than compacting it. Minimal Maintenance - Single moving part, no springs, no motors, no bearings, make Air Blasters easy to maintain for many years. No lubrication is required. More Powerful Air Blast - Lightweight piston, short piston travel, direct blast design, and aerodynamically designed exhaust windows allow the tank to be emptied more quickly creating a stronger, more productive blast. No Leakage - Piston designed to prevent air loss during blast. Polypropylene piston conforms to the valve seat for a superior seal, preventing air seepage between blasts. Air loss can be a problem in blasters using a metal-to-metal seal. Fills Faster - Standard quick fill port allows tank to fill in less than 60 seconds (2.5" & 4.0" discharge models). This makes rapid repeat firing possible when needed. Longevity - Corrosion, abrasion, and impact resistant piston. Coated valve parts resist acid and basic environments. Piston movement engineered to prevent excessive wear. Ease of Service - All parts individually replaceable. If a part becomes worn or damaged, it is not necessary to replace the entire valve. ASME Certified Pressure Vessels - All details of design, materials, construction, and workmanship of each vessel conforms to the ASME Code for Pressure Vessels, Section VIII, Division 1. Documentation available for each Air Blaster upon request. Five Year Warranty
