Key Features & Engineering
Why It's Called a Jet Fan
High-velocity compressed air jets are ejected from the trailing edge of the fan blades — driving blade rotation just like jet exhaust propels an aircraft. The shaft transmits zero torque to the blade; only the air jets on the trailing edge drive the fan. This unique design eliminates shaft loading, reduces bearing stress, and is why these fans (sometimes called "Coppus Blowers") deliver exceptional performance.
T6 Aircraft Aluminium Castings
All castings are heat-treated to T6 aircraft aluminium specification — the same standard used in aerospace structures. This provides maximum strength-to-weight ratio, excellent corrosion resistance, and significantly reduces static electricity buildup versus plastic fan housings — important for operation in flammable atmosphere locations.
Precision Balanced Fan Blades
All four fan blades are precision balanced — eliminating vibration, reducing bearing wear, and extending service life. The hub and four-blade configuration produces adequate static pressure to overcome the resistance of the system being ventilated — essential for pushing air through long flexible ducts into deep tank or vessel spaces.
Guide Vanes — Smooth Axial Flow
The housing is equipped with guide vanes that neutralise the rotational spin of air leaving the fan blades and redirect it into a straight axial direction. This significantly increases fan efficiency, reduces turbulence losses, and improves performance through ducting compared to fans without guide vanes.
Smooth Inlet Bell — High CFM, Low Noise
The smooth inlet bell profile accelerates incoming air smoothly into the fan without turbulence-inducing sharp edges — increasing volumetric efficiency (CFM) and reducing noise levels. Directly contributes to the higher CFM output of Dynaweld fans compared to flat-face housings.
Electro Polished Stainless Steel Guards
Fan guards are electro polished stainless steel — corrosion-resistant, easy to clean, and compliant with the highest duty standards for industrial ventilation equipment. The heavy-duty construction makes Dynaweld Jet Fans the heaviest-duty fans in their class — built for continuous industrial use in demanding environments across the Middle East and Africa.
Applications
| Application | Detail |
|---|---|
| Confined Space Ventilation | Ventilation of tanks, process vessels, columns, reactors, and pressure vessels before and during confined space entry for maintenance and inspection at oil & gas and petrochemical facilities across UAE (ADNOC), Saudi Arabia (Aramco), Qatar (QatarEnergy), and Iraq |
| Welding Fume Exhaust | Continuous fume extraction during welding, grinding, and cutting operations inside tanks, vessels, and enclosed structures — DY20 and DY24 deliver the high air volumes needed to maintain safe atmospheric conditions during active hot work |
| Sand Blasting Operations | Continuous dust and blast media exhaust during internal sandblasting of tanks, columns, and vessel internals during surface preparation for re-coating and lining — minimising visibility impairment and atmospheric hazards |
| Cargo Hold Ventilation | DY24 particularly suited for large cargo hold ventilation on bulk carriers, tankers, and offshore supply vessels during loading, unloading, and maintenance operations in UAE, South Africa, and Nigeria shipyards |
| General Industrial Ventilation | Cooling and fresh air supply to any industrial location with available compressed air — process buildings, transformer bays, substation rooms, motor rooms, and enclosed workspaces across GCC and Africa without electrical power connections |
| Foundries & Sand Blasting | Fume and dust extraction from foundry casting operations, sand blasting, and shot peening enclosures — where the volume and temperature of fumes rule out electric motors |
