Engineered for 60Hz Saudi power grids, extreme desert heat endurance, and heavy continuous-duty cycle applications across KSA factories and commercial facilities.
The Kingdom of Saudi Arabia (KSA) represents one of the most demanding operational environments in the world for industrial ventilation and forced-air extraction equipment. Driven by unprecedented infrastructure growth under Saudi Vision 2030—including major developments such as NEOM, the Red Sea Project, Qiddiya, and expanding industrial hubs in Jubail, Yanbu, Dammam Second Industrial City, and Riyadh—demand for industrial exhaust fans, roof extractors, and heavy-duty centrifugal blowers has surged dramatically.
However, operating air movement machinery in the Arabian Peninsula presents severe thermodynamic, mechanical, and electrical challenges. Standard off-the-shelf ventilation units imported from temperate climate zones routinely suffer from premature motor winding burnouts, bearing grease breakdown, dust infiltration, and rapid casing corrosion. As an established exhaust fan manufacturer and specialized motor factory with over five decades of continuous production history (founded in 1974), our engineering facility delivers custom-configured OEM exhaust ventilation units designed explicitly to conquer Saudi Arabia's microclimate parameters.
In regions like Riyadh, Medina, and Al Ahsa, ambient summer temperatures routinely climb past 48°C to 50°C, with sun-exposed metal rooftop surface temperatures exceeding 70°C. Standard electric motors rated for a nominal 40°C ambient limit experience excessive temperature rise under continuous duty (S1), causing Class F insulation to degrade exponentially. Our specialized exhaust fan motors serving Saudi factories incorporate Class H (180°C) copper wire insulation, high-temperature synthetic bearing greases rated to 200°C, and enlarged external cooling fins to prevent thermal overload shutoffs.
Furthermore, Saudi Arabia's regulatory framework—governed by the Saudi Standards, Metrology and Quality Organization (SASO)—enforces strict energy efficiency mandates (such as SASO IEC 60034-30-1 for rotating electrical machines). Exhaust fan assemblies supplied to Saudi Arabia must balance maximum volumetric airflow performance (CFM / m³/h) against total electrical power consumption (kW), mandating the integration of high-efficiency IE2, IE3, or electronically commutated (EC) brushless motor architectures.
Unlike neighboring Gulf countries that operate primarily on 50Hz, Saudi Arabia's commercial and industrial power distribution network operates exclusively on a 60Hz frequency. Operating a 50Hz motor on a 60Hz supply causes a 20% increase in rotational speed, leading to severe motor overload, altered fan aerodynamic curves, elevated static pressure resistance, and potential mechanical failure.
Our Saudi-dedicated exhaust fan manufacturing line builds all motors with laminations, winding turns, and pole configurations specifically calibrated for 60Hz operation (e.g., 2-pole 3600 RPM, 4-pole 1800 RPM, and 6-pole 1200 RPM nominal speeds). We provide exact dual-voltage capability compliant with Saudi SEC standards: single-phase 220V/60Hz for commercial kitchens and light workshops, alongside 3-phase 220V/380V or 400V/480V/60Hz for heavy industrial manufacturing plants.
Different industrial sectors in KSA require distinct exhaust fan impeller geometry, static pressure capabilities, housing materials, and protective coatings. Our OEM engineering team designs application-specific air movement systems tailored to Saudi operating realities:
High-volume axial wall exhaust fans and roof louvers designed to flush out trapped solar heat gain in steel-clad distribution centers located in MODON industrial zones (Riyadh, Dammam, Jeddah).
Explosion-proof (ATEX/IECEx certified) hazardous area centrifugal exhaust blowers for Saudi Aramco contractor projects, handling volatile hydrocarbon fumes and acid vapors in Jubail and Yanbu.
Backward-curved high-static centrifugal exhaust fans built with out-of-airstream motors for grease, smoke, and heat extraction in high-throughput hotels in Makkah, Madinah, and Riyadh.
Heavy-duty fiberglass and galvanized steel cone exhaust fans engineered for aggressive desert livestock housing, featuring moisture-sealed IP65 motor enclosures.
Compact axial and inline duct exhaust fans providing positive pressure filtered ventilation for power generation enclosures, MV transformer rooms, and switchgear vaults.
Heavy-gauge steel scroll centrifugal blowers fitted with abrasive dust-resistant impellers for aggregate plants, quarry processing, and mining operations across KSA provinces.

As a specialized motor and fan factory with continuous operation since 1974, Delco Fans provides distinct technical advantages over generic trading companies and resellers. We manage the full manufacturing lifecycle in-house—from stator lamination punching and automatic coil winding to dynamic rotor balancing, powder coat finishing, and aerodynamic wind-tunnel testing.
Established in 1974 in Thane, Maharashtra, our facility brings half a century of empirical engineering data to solve severe thermal and mechanical duty challenges for international buyers.
We manufacture our own fractional horsepower (FHP) and three-phase motors. This allows us to tailor coil turns, wire gauges, and stack lengths specifically for Saudi 60Hz power requirements.
To survive airborne sandstorm particulates (Haboob) common in Riyadh and the Eastern Province, our fan housings and motor terminal boxes feature dual-lip oil seals and vulcanized gaskets.
We build exhaust fans according to exact OEM engineering drawings. Keyways, shaft dimensions, mounting brackets, and housing orientations are fully customizable for seamless factory drop-in replacement.
