Operating mode

Control is as simple as possible:

OFF – fan is off

1. - low speed
2. - medium speed
3. - high speed

 

P3-1-300 switches between the pre-set speed leads of the motor. Therefore, it must be used only with a fan whose motor is designed for three-speed operation.

Compatibility

P3-1-300 is designed for three-speed fans.

It is important that the specific fan has separate electrical leads for low, medium, and high speed. If the motor is single-speed and allows adjustment by changing the voltage, another type of controller is required, for example from the RS-1 series.

Installation and protection

P3-1-300 is designed for indoor wall mounting in a suitable mounting box. The manufacturer expressly warns against:

• direct water spraying;
• rain;
• direct sunlight;
• installation directly next to heating appliances and other heat sources. Electrical connection must be carried out with the power supply switched off and by a qualified person.

Operation

The RS-1-400 regulates the speed by changing the voltage supplied to the motor. Operation starts from a pre-set minimum value and allows for a smooth increase up to maximum speed. The minimum speed can be adjusted via a potentiometer on the electronic board.

This is important for fans that should not be reduced below a certain speed to ensure the motor remains stable and properly cooled.

Controlling multiple fans

A single RS-1-400 can control more than one compatible fan simultaneously, if:

the total current of all connected fans is ≤ 1.8 A.

For example, with two fans drawing 0.6 A each, the total load is 1.2 A, which remains within the allowed range.

It is also important to verify that the specific motor is suitable for voltage-based speed control.

Protection

The controller features:

• a replaceable thermal fuse for overload protection;
• a filter against transient electrical interference;
• a casing with IP40 protection. IP40 means the product is intended primarily for dry indoor environments and not for direct exposure to water or outdoor weather conditions.

Air Flow

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 relatively low static pressure. This is where the axial fan performs best – for free discharge through a wall, large openings, or short, low-resistance air ducts.

🔊 Noise

Sound pressure level: 53 dBA at 3 m

This is a high-flow industrial fan, so it is not designed for applications where low noise is the primary priority. For installation in sensitive environments, suitable sound insulation or distancing from the working area may be provided.

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.

Motor and Reliability

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

• built-in thermal protection;
• ball bearings;
• an approximate service life of up to 40,000 hours;
• speed control capability via a compatible controller.

Suitable for

The VENTS OVK 4E 400 can be used for:

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

Installation

The fan is designed for wall mounting and can be positioned on the inside or outside of the wall, depending on the project. The circular mounting plate features pre-drilled holes for fastening.

Since this is an axial fan, for optimal performance, it is best to keep the airflow path before and after the fan as clear as possible.

Speed Control

Speed can be managed via a suitable:

stepped or stepless speed regulator.

The regulator is not a standard part of the kit and must be selected separately according to the motor's electrical parameters.
