Are verified 60Hz models available for Saudi Arabia projects?

Yes. The Automatic Shutter Series (15AAQ1, 20/25/30 AUA, AUHT, AUH), Louver Series (20/25/30 ALA, ALH), and Metallic Series (20/25/30 ASB) all feature verified 220V / 60Hz single-phase ratings delivering 122 to 655 CFM.

Why are the reversible models (RGA/RLA) flagged with a 50Hz warning?

The official manufacturer catalogue documents the reversible pull-cord models (20RGA, 25RGA, 30RGA, 20RLA, 25RLA, 30RLA) exclusively with 220V/230V 50Hz performance curves. They should not be deployed on Saudi Arabian 60Hz electrical supply without prior factory 60Hz model confirmation.

What is the difference between AMCA Watts and IEC Watts?

In the KDK catalogue, AMCA Watts represents electrical input measured at 0 in. H2O static pressure in accordance with AMCA test procedures. IEC Watts reflects standard international electrotechnical measurement. AMCA certified ratings apply to the AMCA test method.

Can KDK plastic wall fans be used in commercial kitchens?

They are suitable for general room ventilation, pantry kitchens, heat, and steam exhaust. However, they are strictly NOT suitable for commercial cooking grease exhaust hoods. Commercial grease hoods require NFPA 96 / UL 762 compliant centrifugal upblast roof fans or dedicated grease-rated centrifugal box fans.

What wall cutout size is required for each fan size?

The required square rough-in wall cutout is 175×175 mm for 15cm (15AAQ1), 250×250 mm for 20cm (20AUA/ALA/ASB), 300×300 mm for 25cm (25AUA/ALA/ASB), and 350×350 mm for 30cm (30AUA/ALA/ASB) models.

How loud are KDK plastic wall exhaust fans?

They are engineered for whisper-quiet residential and office comfort. Sound loudness ranges from 1.0 sone (ultra-quiet, approx. 31 dBA) on models like 30AUH 11 up to 3.6 sones on 25AUA at 60Hz.

What safety features are built into the motor?

All KDK wall fan motors feature an integrated thermal cut-off and thermal fuse that permanently interrupts power if the motor temperature exceeds safe operating limits, eliminating potential fire hazards.

How does the automatic shutter operate?

The rear shutter louvers open automatically when electrical power is supplied to the motor and close tightly via gravity and soft plastic cushions when the fan is turned off, preventing backdrafts, outdoor dust, and pest ingress.

What documentation is available for engineering approval?

Cloud Electricals provides the official KDK wall-mount catalogue PDF, technical submittal cut sheets, dimensional drawings, and Saudi commercial compliance documentation (CR, VAT, ISO, COC) for contractor and consultant review.

Application Check

Is the KDK plastic wall fan suitable for your room?

Evaluate room square footage, required air changes, wall opening cutout, and electrical frequency before ordering.

Good fit

Residential bathrooms, guest toilets, powder rooms, and shower enclosures
Pantry kitchens, home cooking prep zones, and office coffee bars
Commercial retail backrooms, staff change rooms, and laundry closets
Small private offices, clinic consultation rooms, and general storage spaces

Confirm first

Wall opening cutout dimension (175×175 mm up to 350×350 mm depending on size)
Electrical supply: verify 220V 60Hz single-phase network availability
Front grille preference: open automatic shutter vs. slim protective louver
Reversible model check: RGA/RLA catalog curves are 50Hz (confirm 60Hz availability before order)

Use another documented fan

Commercial kitchen grease exhaust hoods (select Upblast Roof Fan or Centrifugal Box Fan)
High-pressure industrial factories/warehouses (select KDK Steel Square Fan or TAT LDSF)
Long ducted multi-room ventilation networks (select Inline Duct Fan)
Explosion-proof or ATEX-classified chemical vapor zones

Commercial kitchen application boundary: Kitchen application boundary: KDK plastic and metallic wall fans are engineered for ambient residential and pantry kitchen ventilation, heat, steam, and odor expulsion. They are strictly NOT designed or approved for commercial cooking grease exhaust hoods. Grease-heavy commercial cooking requires NFPA 96 / UL 762 compliant centrifugal upblast roof fans or dedicated grease-rated centrifugal box fans.
