Stock Range of RS In-Line Duct Fans – Buy Online

Axair Fans offers a stock range of plastic inline duct fans, manufactured by Rosenberg with EC or AC motors. An ATEX version of the RS315 (315mm inlet & discharge spigot) is also available on request, coded Ex II 3G IIB T3(x) for category 3 Zone 2.

Our ‘RS’ range of AC in-line duct fans are fitted with the latest generation of high efficiency backward curved motorised impellers, with profiled blades for high airflow and lower noise, combined with specially engineered resilient plastic outer casings featuring guide vanes (straightening the airflow & reducing noise turbulence), these are amongst the quietest while maintaining high airflows (230 to 1725m³/h free air).

All fan motors are thermally protected and are electronically speed controllable. The connector box is moulded on the outside of the casing offering IP44 particle and splashed water protection. The fans come available in all industry standard metric spigots diameter 100 up 315mm. Impellers up to Ø250 are made of plastic, the RS315/L being fitted with metal impellers. The Inlet and outlet side come with duct connection for standard round ducts, and can be mounted in any position.

The fans are balanced according to quality level G 2.5, DIN/ISO 1940 on two levels. Furthermore, they come fitted with maintenance free ball bearings, closed on both sides, therefore sealed for life. Manufactured to ISO 9001. The rotor comes painted to resist corrosion and the integrated connection box comes with IP44 ingress protection and in addition is a Class F insulated motor. The motor protection is integrated and is signalled via a digital output or a tachometer output. Our ‘RS’ range are powered by external rotor motor based fans which are 100% speed controllable.

Inline Duct fans such as the ‘RS’ Range are traditionally used for ducted ventilation systems for industrial, horticultural and electronic ventilation such as spray paint booths, health centres and Offices. Our range of EC in-line duct fans are available in all industry standard metric spigots diameter 100 up 355mm. come available in the following industry standard spigot sizes 160, 200, 250, 315 and 355. They have a lower consumption compared to traditional AC alternatives and contain all the usual EC features, such as tacho output (speed sensor), and easy speed controllability by 0-10VDC signal or PWM. If you were to compare an EC in-line duct fan against a similar size AC version, R315L (AC) vs R315G (EC). The AC version has a power consumption (at free air) of 0.317kwa and the EC 0,194kwa.

The AC version is also slightly more powerful (max air 1750m³/h / max pressure 700Pa) than the EC (1500m³/h max / 640Pa Max). If both fans are operated in a typical commercial application, operating point 900m³/h at 300Pa. The fan will operate at full speed during 8 hours per day and run at half speed the rest of the time, 50 weeks per year, 7 days per week.
