Technical Specifications:
The document provides technical specifications for the G-BH1 series side channel blowers, which can function as both vacuum pumps and compressors. The performance curves are based on air at 15°C and atmospheric pressure of 1013 mbar, with a tolerance of ±10%. The equipment is suitable for continuous operation and complies with EN 60034-1 standards, as well as the 2006/42/EC and 2006/95/EC directives.

Performance and Operation:
The blowers are designed for both vacuum and compressor operations, with motors available in protection category IP 55 and insulation class F. They are UL and CSA approved. The document includes performance curves for different frequencies (50 Hz and 60 Hz) and voltage ranges, indicating the power consumption, pressure differences, and temperature rise of conveyed air.

Electrical and Mechanical Details:
The motors comply with EN 60 034-1 / -2 / -30 standards and have a thermal class F. Tolerances for three-phase motors are +/-10% for fixed voltage and +/-5% for voltage range motors. Single-phase machines have a +/-5% tolerance. Frequency tolerance is +/-2% maximum.

Sound and Safety:
The sound pressure level is measured according to EN ISO 3744, with a tolerance of ±3 dB(A). Relief valves are available to limit differential pressure. The equipment is designed to meet safety and operational standards, ensuring reliable performance.

Ordering Information:
The document provides selection and ordering data, including type numbers, frequency, voltage, current, power, pressure, sound pressure level, and weight. It notes that changes in performance data and weights may occur without prior notice.
