Energy Saving High Thrust Jet

Meech air amplifiers use the Coanda and Venturi effects to entrain large volumes of ambient air using a small compressed air input. Compressed air enters through a narrow annular gap and adheres to the profiled internal surface (Coanda effect), creating a low-pressure zone that draws in surrounding air (Venturi effect). The result is an amplification ratio of 4:1 to 25:1 — meaning up to 25 parts ambient air for every 1 part compressed air. Air amplifiers are available in 5 sizes with outlet diameters from 18 mm to 100 mm, manufactured in aluminium or stainless steel. Noise levels are approximately 78 dBA at the 51 mm model. Applications include: cooling hot products after moulding or extrusion, drying after washing or coating, blow-off of particles and debris, ventilation of confined spaces, light conveying of small parts, and HVAC integration for directed airflow.

A vortex tube is a device with no moving parts that separates compressed air into a cold stream and a hot stream simultaneously. Compressed air enters the tube tangentially at high pressure, creating a rapidly spinning vortex. The outer layer of the vortex exits one end as hot air; the inner core reverses direction and exits the other end as cold air — up to 50 °C below the inlet temperature. This is the Ranque-Hilsch effect. Meech vortex tubes are manufactured in stainless steel and operate optimally at 60-100 PSI (4-7 bar) inlet pressure. They are available in two sizes with 10 different generator models, each producing a different cold/hot air ratio and flow rate. Vortex tubes are the core technology behind Cabinet Coolers and Coldstream Air Guns.

Meech air amplifiers use the Coandă effect to entrain ambient air, amplifying the volume of airflow up to 25:1 relative to the compressed air input. A small volume of compressed air passes through a precisely engineered annular gap, creating a high-velocity jet that adheres to the contoured surface and draws in surrounding ambient air. The result: a large volume of high-velocity air from a small compressed air input. This reduces compressed air consumption by 60-80% compared to open tubes or nozzles delivering the same airflow volume. Air amplifiers are used for cooling, drying, blow-off, ventilation, and conveying applications where compressed air cost is a concern.
