Axial single-phase fan VENTS OVK 4E 400 – Ø400 mm, 3580 m³/h

The OVK 4E 400 is part of the VENTS OVK series of low-pressure industrial axial fans. The design with a round mounting plate allows direct installation in a suitable wall opening, and the fan can operate both for extract and supply air .

The model uses a 4-pole single-phase asynchronous motor with built-in overheating protection and ball bearings. The manufacturer indicates a service life of the bearings of up to about 40,000 hours of continuous operation . The speed can be controlled with a suitable external regulator, which is purchased separately.

Dimensions

Air flow rate

Up to 3580 m³/h at 50 Hz

This makes the OVK 4E 400 suitable for applications where a large volume of air is required at a relatively low static resistance . This is where the axial fan is at its strongest – in free discharge through a wall, large openings or short and low-resistance air paths.

🔊 Noise

Sound pressure level: 53 dBA at 3 m

This is a high flow industrial fan, so it is not intended for applications where low noise is the main priority. When installed in sensitive environments, appropriate sound insulation or distancing from the work area may be considered.

Operating temperature range

The model can transport air with a temperature of approximately:

-30°C to +60°C

This makes it suitable for a wide range of technical and industrial conditions.

Engine and reliability

The OVK 4E 400 uses a 4-pole asynchronous electric motor with:

• built-in thermal protection;
• ball bearings;
• approximate resource up to 40,000 hours ;
• possibility of speed regulation via a compatible controller.

Suitable for

VENTS OVK 4E 400 can be used for:

• industrial ventilation;
• warehouses and production facilities;
• technical premises;
• greenhouses and grow spaces;
• garages and workshops;
• direct air outlet through an external wall;
• tributary systems;
• systems requiring high flow and low resistance.

Installation

The fan is designed for wall mounting and can be placed on the inside or outside of the wall depending on the project. The round mounting plate has holes for fixing.

Since this is an axial fan, for optimal performance it is good to have the air path before and after it as free as possible.

Speed regulation

The speed can be controlled by appropriate:

step or smooth speed regulator.

The regulator is not a standard part of the kit and must be selected separately based on the electrical parameters of the motor.
