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.

Frequently Asked Questions

Why is it called a "jet fan" and how does it work?

Dynaweld Jet Fans are driven by high-velocity compressed air jets ejected from the trailing edge of the fan blades — exactly like a jet engine where rear exhaust propels the aircraft forward. The shaft transmits no torque; only the air jets drive blade rotation. This means shaft bearing loads are far lower than conventional motor-driven fans. Only the shaft, bearings, and fan blade rotate — the compressed air does all the work. Sometimes called "Coppus Blowers" after an early manufacturer of this fan type.

What is the difference between the DY20 and DY24?

The DY20 is 24.5 inches diameter (44 kg) with a 3/4" NPT air inlet and delivers up to 10,420 CFM at 100 PSI. The DY24 is larger at 31.25 inches diameter (59 kg) with a 1" NPT inlet and delivers up to 16,136 CFM at 100 PSI — 55% more airflow. Both share the same 150 PSI maximum pressure and 12 inch depth. Choose DY24 for larger vessels, higher air change requirements, or longer duct runs requiring more static pressure.

Are Dynaweld Jet Fans safe for hazardous areas with flammable atmospheres?

Yes. Dynaweld Pneumatic Jet Fans have no electrical motor, no electrical components, and no electrical ignition sources. The T6 aircraft aluminium castings significantly reduce static electricity risk compared to plastic fans. They are suitable for hazardous locations including confined spaces with flammable gas or vapour atmospheres, where electric fans are prohibited by safety regulations across oil & gas, petrochemical, and marine operations throughout the Middle East.
