AIR SYSTEMS INTERNATIONAL

Air Systems International is a manufacturer of ventilation, respiratory air supply, and confined space safety equipment. The company's product line is built around two core needs in industrial environments: moving air safely through hazardous or enclosed spaces, and delivering breathable air to workers using supplied-air respirators (SAR). 3G Electric supplies 131 SKUs from this brand, covering explosionproof blowers, pneumatic venturi blowers, cascade kits, airline hoses, and portable cooling systems. The product families are designed for applications where standard ventilation or air supply equipment may not meet electrical classification or pressure requirements.

About AIR SYSTEMS INTERNATIONAL

Air Systems International is a manufacturer of ventilation, respiratory air supply, and confined space safety equipment. The company's product line is built around two core needs in industrial environments: moving air safely through hazardous or enclosed spaces, and delivering breathable air to workers using supplied-air respirators (SAR). 3G Electric supplies 131 SKUs from this brand, covering explosionproof blowers, pneumatic venturi blowers, cascade kits, airline hoses, and portable cooling systems. The product families are designed for applications where standard ventilation or air supply equipment may not meet electrical classification or pressure requirements.

The ventilation side of the line includes explosionproof centrifugal blowers and pneumatic venturi blowers. Explosionproof centrifugal blowers are available with 3/4 hp and 1-1/2 hp motors operating at 115 V AC, with duct diameters of 8 in and 12 in. These units are intended for confined space ventilation in tanks, vaults, and manholes, and some models include conductive duct kits or duct canisters. Pneumatic venturi blowers operate without electricity, using compressed air at up to 140 psi inlet pressure, and include a static grounding lug. They are used for industrial ventilation, fume extraction, and material conveying in confined or hazardous areas where electrical equipment is restricted.

The respiratory air supply family includes cascade kits, airline hoses, and portable cooling systems. Cascade kits are configured for SAR compressors and ambient air pumps, with three-cylinder assemblies and CGA-346 or CGA-347 fittings. Kits include a regulator, relief valve, outlet manifold assembly, connecting whip with check valves, and a low-pressure whistle. Airline hoses are available in 10 ft lengths with 1/2 in inside diameter and 1/2 in Hansen fittings, rated to 250 psi. Portable airline cooling systems are ice-based and provide 4 to 8 hours of cooling for low-pressure (5-20 psi) or higher-pressure (40-120 psi) airline respirators, using 1/4 in Schrader or Hansen fittings.

Technical buyers specifying this line should note the emphasis on pressure ratings, fitting standards, and electrical classifications. Explosionproof blowers carry specific voltage and horsepower ratings, while pneumatic blowers avoid electrical components entirely. Cascade kits and hoses use standardized fittings (CGA, Hansen, Schrader) to integrate with existing SAR systems. Materials include plastic for cooling units and conductive components for static dissipation in hazardous areas.

3G Electric supports the Air Systems International line by stocking a broad range of SKUs and providing specification-level product data. The catalog includes part numbers, pressure ratings, duct sizes, fitting types, and included components, allowing maintenance and procurement teams to match equipment to site requirements. For global operations, 3G Electric ships these products internationally, with quote-based ordering for configured kits and replacement parts.

Common Applications

  • Confined space entry — Explosionproof centrifugal blowers (e.g., CVF12EXP15, SVB-E8XCUP) for ventilating tanks, vaults, and manholes.
  • Hazardous area ventilation — Pneumatic venturi blowers (e.g., ASI-2900) for fume extraction and material conveying without electrical components.
  • Respiratory air supply — Cascade kits (e.g., CBA3-346NB, CBA3-347NB) for SAR compressors and ambient air pumps in industrial settings.
  • Worker cooling — Portable airline cooling systems (e.g., BACB-196LP, BACB-196) for SAR users in high-temperature environments.
  • Airline connections — SAR airline hoses (e.g., H-10-5) for supplying compressed air to respirators in industrial facilities.

Guides & Resources

Frequently asked questions

Common questions about AIR SYSTEMS INTERNATIONAL from 3G Electric.

What is the maximum inlet pressure for Air Systems International venturi blowers?

Air Systems International pneumatic venturi blowers, such as the ASI-2900, are rated for a maximum inlet pressure of 140 psi. They use a 1 in NPT air inlet and include a static grounding lug. These blowers operate on compressed air rather than electricity, making them suitable for hazardous locations where electrical equipment is restricted. They are commonly used for industrial ventilation, fume extraction, and material conveying in confined spaces.

What fittings are used on Air Systems International cascade kits for SAR compressors?

Air Systems International cascade kits are available with CGA-346 or CGA-347 universal fittings. For example, the CBA3-346NB uses CGA-346 fittings, while the CBA3-347NB uses CGA-347 universal fittings. Both are three-cylinder kits designed for SAR compressors and ambient air pumps. Each kit includes a regulator, relief valve, (4) outlet manifold assembly, connecting whip with check valves, and a low-pressure whistle. The fitting type must match the compressor or pump connection.

What are the power and duct size options for Air Systems International explosionproof centrifugal blowers?

Air Systems International explosionproof centrifugal blowers are available with 3/4 hp or 1-1/2 hp motors, both operating at 115 V AC. Duct diameters include 8 in and 12 in. Models may include a conductive kit or a duct canister. For example, the SVB-E8XCUP has a 3/4 hp motor, 8 in duct, and includes the SV-CUPCND conductive kit. The CVF12EXP15 has a 1-1/2 hp motor, 12 in duct, and includes a 15 ft duct canister. These blowers are used for confined space ventilation in tanks, vaults, and manholes.

What is the cooling duration and pressure range for Air Systems International portable airline cooling systems?

Air Systems International portable airline cooling systems provide 4 to 8 hours of cooling. They are ice-based and constructed of plastic. Two pressure ranges are available: low-pressure models for 5-20 psi constant flow airline respirators, and higher-pressure models for 40-120 psi airline respirators. Fitting types include 1/4 in Schrader for low-pressure units and 1/4 in Hansen for higher-pressure units. These systems are used with SAR setups to reduce air temperature for worker comfort.

What are the specifications of Air Systems International SAR airline hoses?

Air Systems International SAR airline hoses, such as the H-10-5, are 10 ft long with a 1/2 in inside diameter. They have 1/2 in Hansen fittings and are rated for a maximum pressure of 250 psi. The hose is yellow and includes male and female couplings. These hoses are used to supply compressed air in industrial environments, connecting respirators to air sources. The Hansen fittings allow for quick connection and disconnection.
