VENTS OVK 4E 400 is a professional axial fan with a circular mounting plate, designed for supply and exhaust ventilation systems requiring a high air flow rate and relatively low system resistance. The model features a diameter of Ø400 mm, a maximum air flow of 3580 m³/h, a power output of 180 W, and a single-phase power supply of 230 V / 50 Hz. It is suitable for wall mounting in industrial, technical, warehouse, greenhouse, and other ventilation applications.

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

The model utilizes a 4-pole single-phase asynchronous motor with built-in thermal overheating protection and ball bearings. The manufacturer specifies a service life for the bearings of up to approximately 40,000 hours of continuous operation. The speed can be controlled using a suitable external controller, which is purchased separately.

Dimensions

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.

Key Advantages

✔️ High air flow – up to 3580 m³/h
✔️ Large operating diameter – Ø400 mm
✔️ Only 180 W nominal power
✔️ Single-phase 230 V power supply

VENTS TT PRO 250 P is a high-performance two-speed inline fan with a mixed-flow axial-centrifugal impeller, designed for ventilating spaces that require high airflow and high static pressure. It is suitable for ventilation systems in greenhouses, grow rooms, production and commercial facilities, as well as residential applications. Thanks to its compact design and removable motor block, the fan is easy to install, service and clean.

VENTS TT PRO 250 P is part of the professional TT PRO series, developed for ductwork with high aerodynamic resistance. The combined axial and centrifugal fan technology provides significantly higher pressure than standard axial fans while maintaining high performance and relatively low noise levels.

The housing is made of high-quality impact-resistant polypropylene plastic, corrosion-resistant and suitable for operation in humid environments. The fan is equipped with a two-speed single-phase AC motor mounted on double-sealed ball bearings, providing a service life of up to 40 000 hours of continuous operation. Built-in thermal protection prevents motor overheating and automatically switches it off in the event of overload.

One of the model's main advantages is the removable central motor block, which allows easy servicing and cleaning without removing the ductwork. This significantly reduces maintenance time and makes ventilation-system upkeep easier. The fan can be installed horizontally or vertically, in any position, directly into round ductwork with a diameter of 250 mm.
