greenco side channel blowers

The Greenco range of side channel blowers is available in both single-stage and two-stage units. The blowers are supplied as complete units and are designed for easy installation.

GREENCO 2RB

  • The Greenco 2RB range can be used as either a vacuum pump or compressor and is designed for continuous operation across its stated performance range.
  • The motors are available for 50 Hz and 60 Hz input voltage, with IP54 protection, and are approved according to EC and RoHS requirements.
  • The motors are designed according to DIN EN 60034 / IEC 34-1 and temperature class F.
  • For three-phase machines, voltage tolerances are ±10% for fixed voltage and ±5% for voltage range. Single-phase machines are designed with ±5% tolerance. Frequency tolerance is a maximum of ±2%. Vacserve

GREENCO G-4RB

  • The G-4RB range complies with applicable standards including the Low Voltage Directive (LVD) 2006/95/EC, EN 60034-1-2004 for rotating electrical motors and relevant electromagnetic compatibility standards.
  • Electric motors also comply with UL 1004-1 where applicable.
  • Relief valves are available to limit differential pressure.
  • Sound-pressure levels are measured according to DIN EN 21680 at a distance of 1 metre.
  • The motors are designed according to DIN EN 60034 / DIN IEC 34-1 and temperature class F.
  • Three-phase machines have voltage tolerances of ±10% for fixed voltage and ±5% for voltage range. Single-phase machines have a ±5% tolerance, while frequency tolerance is a maximum of ±2%.

PRESSURE RELIEF VALVES

The Greenco Relief Valve is manufactured from zinc-plated mild steel and is designed to protect blowers against overheating when operating in a blocked-off condition during either vacuum or pressure operation.

The valve can be set by the customer according to the required vacuum or pressure level.

These valves are commonly used with:

Regenerative Blowers • Positive Displacement Blowers • Vacuum Pumps

Work Principle

The relief valve is installed on the inlet or outlet of the side channel blower.

When the operating pressure or a pressure surge exceeds the rated pressure of the blower, the relief valve opens and releases the excess pressure to help protect the blower.

Once the operating pressure returns to a safe level, the valve closes gradually to prevent another pressure surge.
