Flexibility

RS fans are designed as low profile and intended to use for supply or extract air and can be installed in any position. This ensures that the fans can be used in a variety of commercial applications. Rather high operation temperature predetermines fans to work in areas with high demands. Casing of insulated model RSI has perfect acoustic and thermal insulation capacity.

Reliability

The combination of reliable casing, composite impeller and motor construction ensure to minimize the need for maintenance of the fans and allows long continuous operation.

Thanks to swing-out service lid, the fan is easy to maintain.

Performance

High performance impellers together with high efficient external rotor motors are designed to ensure high-level performance to minimize power consumption and maximize efficiency.

Easy installation

Thanks to standard flanges and variety types of recommended accessories as flexible connections, filters, heaters, coolers, dampers, etc. ensures easy installation.

Features

Casing

Casing made of galvanised sheet steel, corrosion class C3. Casing of insulated model RSI has 50 mm acoustic and thermal insulation made of rockwool. Motor with impeller is mounted on swing out service lid. Connection flanges are size PG20. Fans are equipped with an external terminal box with protection class IP54.

Impeller

RS/RSI fans use single inlet radial impeller with backward curved blades. Impeller made of lightweight, hard-wearing fiberglass reinforced composite material, dynamically balanced and paired with corresponding external rotor motors.

Motor

Depending on type, RS/RSI fans are equipped with AC or high efficient EC external rotor motors. All motors are suitable for 50Hz and 60Hz.

Motor protection

Fans with AC motors small sizes up to 50-25 have integrated thermal protection with manual (electrical) reset.

Fans with AC motors bigger sizes have prewired integral thermal contacts (TK) with leads to an external motor protection device (separate accessory).

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

Control

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

Depending on type, fans with EC motor are also equipped with ModBus communication or alarm signal.   

AC motor can be controlled by 5-step, stepless speed regulator or frequency converter from the wide range of recommended electrical accessories.

Installation

RS/RSI fans can be installed indoor in any position. All models have standard inlet and outlet PG20 flanges to simplify stand-alone installation or together with other accessories. For preventing vibration to the duct it is recommended to use flexible connection.
