Flexibility

The DVN/DVNI fans are intended to use for extract air with vertical discharge.

DVN/DVNI are the smart choice when requirements are higher than average, in applications such as extraction from kitchens, process air systems and industrial ovens. They are suitable for continuous air flow temperatures up to 120°C.

The fans are designed to handle high volumes at medium pressure without generating excessive noise.

Reliability

The casing is made out of seawater-resistant aluminium with an inside galvanised steel frame is hard-wearing.

The combination of casing and motor construction ensures to minimize the need for maintenance of the fans and allows long continuous operation.

Performance

High-performance aluminium impeller together with highly efficient motors are designed to ensure high-level performance to minimise power consumption and maximise efficiency.

Accessories

DVN/DVNI fans can be selected together with variety types of accessories as roof sockets, tilting devices, dampers, etc.

Features

Construction

The Casing is made from seawater-resistant aluminium. Base frame manufactured from galvanised steel with integrated inlet cone. Integrated bird guard manufactured from powder coated, galvanised steel.

DVNI is with 50 mm mineral wool acoustic and thermal insulation.

Impeller

The DVN/DVNI fans use radial impeller with backward curved blades. These are made out of aluminium, dynamically balanced and paired with corresponding IEC motor with efficiency IE3 or EC motor.

Motor

Depending on the type, DVN/DVNI fans are equipped with AC or EC external rotor motors. Motors are suitable for 50Hz and 60Hz.

Motor protection

Depending on the type, AC motors have an integrated thermal protection with manual (electrical) reset, prewired integral thermocontact TK or thermistor PTC with leads to a motor protection device.

Fans with EC motors have an integrated electronic thermal protection including locked-rotor protection and soft-start.

Control

EC motors with built-in potentiometer to adjust working point can be also controlled by external signal 0-10V.

EC motors, depending on the type are also equipped with ModBus communication or alarm signal.   

AC motors can be controlled by 5-step, stepless speed regulator, D/Y switch or frequency converter.

Installation

The DVN/DVNI are for outside installation.
