About Air Systems International
The brand's extensive catalogue includes confined space venturi blowers, supplied air compressors & ambient air pumps, supplied air compressors and ambient air pumps, hose safety cables, SCBA and breathing air cylinders, respiratory airline hoses, saddle vents, cascade airline kits and manifolds, confined space fan and blower accessories, motor driven and hand crank hose reels, replacement sensors, air cleaner filters, duct and fittings and airline cooling systems. Air System International's confined space venturi blowers use saturated steam or compressed air as a power source for extracting hazardous fumes / vapours and are used in underground storage tanks and below-the-ground locations. They feature a sturdy galvanised steel body and aluminium base for structural rigidity and corrosion resistance. Air Systems venturi blowers have an effective extraction across refineries, power plants and the steel industries. The brand's air filtration systems have an air compressor that compresses ambient air for respirator users. The compressed air passes through a high-quality filter to remove contaminants, ensuring clean and safe breathing air. They come with a carbon monoxide (CO) monitor that continuously checks for CO presence, providing alerts if levels exceed safety limits. These systems feature a safety visual flowmeter that verifies airflow, ensuring an adequate air supply. They are equipped with an inline compressed air purification (CPO) monitor that assesses air quality by removing contaminants, moisture and oil, providing real-time feedback. These filtration systems have a solid aluminium block manifold that serves as a central distribution point for the compressed air, facilitating proper routing to system components.

Air Systems International Competitive Advantages
Breather Box Air Filtration
Breather Box is a portable filtration system designed to provide Grade-D quality breathing air for workers. It filters incoming air from a compressor, monitoring CO and oxygen levels. It has three filtration stages, removing water, particulates, oils, mists, ultra-fine particles, organic vapours and odours. This breather box has filter change indicators included in it. Filtration efficiency is 99.99% at a minimum particle size of 0.01 micron. This system includes a CO monitor with battery, DC or AC power options, with audible and visual alerts. It comes with point-of-attachment (POA) boxes to extend respirator usage.
Frequently Asked Questions
What are ambient air pumps?
They are oilless vane air compressors that operate at low pressure. The pressure in these pumps does not exceed 15 psi.
Do air compressors increase air temperature?
Yes, as these compressors compress air into a smaller volume, the air heats up. This increases the pressure and temperature of the air.
What is the difference between Air Systems International air-powered confined space fans & blowers and electric confined space fans & blowers?
Air-powered units rely on compressed air as their power source, offering versatility in hazardous locations and off-grid settings. They are lightweight and portable, making them easy to transport. In contrast, electric fans & blowers are powered by electricity from outlets or batteries, making them suitable for indoor or urban environments. They provide continuous operation and often feature variable speed settings. Electric units are generally more power-efficient and emit no emissions, while air-powered units generate less noise.

What is the significance of this brand's swivel connectors?
Air Systems International swivel connectors are ideal for installations in wet environments or facilities with a requirement for long vacuum hoses. They feature a built-in pressure relief valve to restrict water lifts beyond 160 inches for preventing tank collapse. They come with an ON / OFF flow valve and a pressure gauge for enhanced performance.
What factors should I consider while choosing airline filtration and CO monitors?
- Consider the effectiveness of removing contaminants and providing clean air.
- Ensure the system can handle the required airflow volume.
- Look for multiple stages of filtration for enhanced effectiveness.
- Monitor filter condition with built-in indicators.
- Accurately detect and measure CO levels.
- Evaluate battery, DC and AC power compatibility.
- Ensure audible and visual alarms for high CO levels.
- Monitor CO levels from a central location.
- Verify adherence to safety regulations.
- Consider user-friendly installation, operation and maintenance.
What is the difference between a breathing air compressor and a plant air compressor?
Breathing air compressor systems are designed for the purpose of providing respirator-compatible air. These systems are tailored to meet the specific requirements of respirator use, including considerations such as compressor size, FDA Food-grade lubricating oil, Grade-D filtration, CO monitoring, refrigerated dryer, receiver tank with condensation drain and an appropriate air distribution system. While a plant air compressor is not specifically designed or optimised for respirator use and may not have these specialised features.
