What is the difference between OV, OVK, and VKF fans?

All three share the same aerodynamic motor and impeller platform from VENTS: OV features a square mounting plate for flat wall surface installation, OVK has a round mounting plate for circular wall openings, and VKF has dual round flanges for direct inline connection into circular ventilation ductwork.

Are 60Hz configurations available for Saudi Arabia projects?

Yes. Models from 200 mm to 630 mm have verified factory 60Hz ratings for standard Saudi Arabian 220–240V single-phase and 380–415V three-phase electrical supplies. Models 710 mm and 800 mm are listed in the manufacturer catalog at 50Hz.

What are the operating limits for low static pressure?

VENTS OV axial fans are designed for low-pressure systems (0 to 100 Pa). When discharging directly through an open wall or short wall sleeve with gravity shutters, airflow is maximized. Connecting OV fans to long, high-resistance duct runs will result in significant airflow reduction.

Can VENTS OV fans be used for smoke pressurisation?

The manufacturer catalog mentions OV/OVK fans for pressurisation in smoke ventilation systems. However, any life-safety use requires project-specific engineering review, design duty calculations, control and damper logic, power backup, and formal consultant and local civil defense approval. The standard catalogue continuous operating temperature (-30°C to +50°C at 60Hz) is for normal ventilation and does not constitute a high-temperature emergency fire rating.

Can the fan speed be controlled?

Yes. Single-phase models (OV 2E / 4E / 6E) can be controlled smoothly using thyristor electronic speed controllers (e.g. RS-1-400) or stepped using autotransformer controllers. Three-phase models (OV 4D / 6D) are controlled via multi-step autotransformers.

Is the OV series suitable for outdoor wall mounting?

Yes. The steel casing and impeller have a protective polymeric powder coating, and the motor is rated IP44. For exposed exterior facades, coordinating an external weather hood, rain cowl, or gravity backdraft shutter is recommended to prevent water and sand ingress.

Can OV fans be used for commercial kitchen grease exhaust?

No. Standard VENTS OV axial fans are strictly for clean or ambient non-hazardous air. Commercial kitchen cooking hoods require grease-rated, high-temperature centrifugal upblast roof fans or dedicated grease-rated centrifugal box inline fans compliant with NFPA 96.

What wall opening size is required for installation?

The circular wall cutout diameter should be approximately the impeller diameter (D) + 15 mm. The square mounting plate outer dimensions (B) range from 312×312 mm for the 200 mm model up to 800×800 mm for the 630 mm model.

What documentation is available for engineering submittal?

Cloud Electricals provides the official VENTS OV / OVK / VKF technical catalog PDF, dimensional cut sheets, 60Hz performance curves, and Saudi commercial compliance documentation (CR, VAT, ISO, COC) for contractor and consultant review.

Application Check

Is the VENTS OV wall axial fan suitable for your facility?

Evaluate required airflow, operating static pressure, electrical supply, and airstream characteristics before selection.

Good fit

Industrial factories, manufacturing halls, and large production workshops
Commercial warehouses requiring direct wall air supply or stale heat extraction
Electrical transformer rooms, switchgear bays, and elevator equipment rooms
General service corridors, utility areas, and commercial storage facilities

Confirm first

Operating static pressure must remain low (< 50–120 Pa) to prevent airflow collapse
Wall opening cutout diameter (D + 15 mm) and square plate outer size (B × B mm)
Site electrical supply (1-Phase 230V 60Hz or 3-Phase 400V 60Hz)
External speed controller matching (thyristor for 1-phase / autotransformer for 3-phase)
Transported air operating temperature within continuous bounds (-30°C to +50°C at 60Hz)

Use another documented fan

Commercial kitchen grease exhaust hoods (select Upblast Roof Fan or Centrifugal Box Fan)
High-temperature emergency smoke extract (select certified VDO Smoke Extraction Fan)
High-resistance duct systems with multi-branch grilles (select Inline Duct Fan)
Explosion-proof or ATEX-classified flammable solvent or spray painting booths

Smoke pressurisation & life-safety engineering boundary: The catalogue mentions OV/OVK for pressurisation in smoke ventilation systems; any life-safety use requires the exact model's approval, design duty, normal/emergency operating mode, controls, power, damper logic and consultant/authority acceptance. The catalogue's normal air-temperature limits (-30°C to +50°C at 60Hz) are not a fire-rating.
