Aerotech Fans
Loading industrial-grade components...
AeroTech's Ring Fan is a heavy-duty wall-mounted axial flow fan engineered to move large volumes of air efficiently along the axis of rotation, making it ideal for industrial and commercial ventilation. Constructed from superior-grade materials with a heavy-gauge rolled galvanized steel housing featuring continuous welded seam and epoxy coating, these fans offer reliable performance and long service life in demanding environments. The aluminium/PP-GL impellers are selected for maximum airflow and low sound, with adjustable pitch angles for exact performance matching.
Available in sizes 300mm to 1600mm diameter with 4, 6, 7, 8, or 11 blade configurations, the Ring Fan delivers up to 1,30,000 CMH airflow at up to 45" wg static pressure. Standard motors are 415V ±10%, 50Hz, IE2/IE3 TEFC conforming to IS:325/1996 & IS 12615:2011. Suitable for operating temperatures from -60°C to +245°C, with high temperature testing at 250°C for 2 hours and 300°C for 1 hour.
IoT-Ready and VFD Compatible for modern smart factory integration.

Adjustable pitch angles for exact performance matching. Fixed pitch also available.
Gravity Louver
Self-acting weather-resistant damper that opens automatically when fan operates and closes when stopped. Prevents backdraft, rain, dust, and pests.
Rain Cowl with Bird Mesh
Robust wire guard installed at inlet or outlet to prevent birds, rodents, and animals from entering the duct or fan housing.
Sound Attenuator
Duct silencer/muffler for HVAC ductwork designed to reduce noise transmission from equipment into occupied spaces or between zones.
| Model | Air Volume (CFM) | Static Pressure (in.wg) | RPM (Max) | Motor (HP) |

| RF-500 | 14,000 | 120 | 1,440 | 3 |
| RF-900 | 42,000 | 230 | 960 | 10 |
| RF-1250 | 82,000 | 300 | 720 | 20 |
Marine engine room tube axial fans require a minimum IP56 or IP66 motor rating to survive continuous salt-spray and moisture ingress. The motors must be Totally Enclosed (TEFC or TENV) and the casings should be hot-dip galvanized or marine-grade aluminum.
Blade Pass Frequency (BPF) is calculated by multiplying the fan's RPM by the number of impeller blades, then dividing by 60. Identifying the BPF is critical for acoustic engineers to design perfectly tuned cylindrical silencers that attenuate the exact tonal noise generated by the fan.
While 304 stainless steel resists general oxidation, it is highly susceptible to chloride pitting in salt-spray environments. 316L Stainless Steel contains molybdenum, which drastically increases its resistance to chloride corrosion, making it mandatory for marine and offshore ventilation systems.
