Gardner Denver Elmo Rietschle 2BH1 (G-BH1)
Elmo Rietschle 2BH1 side channel blowers from the G-BH1 series, for vacuum or pressure, with a 50/60 Hz IP55 three-phase motor and a variant with integrated frequency converter.
The G-BH1 series consists of Elmo Rietschle side channel blowers, a brand of Gardner Denver, which work on vacuum or pressure and have an integrated three-phase motor (IP55, insulation class F). The 2BH1 300 data sheet (edition 02/2022) presents the variant with a standard motor and the variant with an integrated frequency converter, supplied at 400 V, with PROFIBUS, CANopen, PROFINET, SERCOS 3 or EtherCAT interfaces.
The type is read from the nameplate: 2BH1 followed by the size group (for example 300) and an order number with a suffix, whose format differs between editions. The series includes several sizes; the motor power, current and weight for each size are confirmed to you by order number. For a quotation, please send us the complete order number from the blower nameplate, together with the voltage, frequency and duty (vacuum or pressure); we confirm the exact type and availability in the quotation.

Frequently asked questions
Why do order numbers differ between 2BH1 blowers of the same size?
The format of the order number changed between editions of the data sheets; edition 02/2022 of the 2BH1 300 data sheet uses numbers of the form 2BH1300-1AP16. For a replacement, the order number on the nameplate of the existing blower is the one that counts; you can send us a photo of the nameplate and we confirm the equivalence in the manufacturer's documentation.
What does the variant with integrated converter mean?
The 2BH1 300 data sheet from 2022 presents, besides the standard motor, a variant in which the frequency converter is integrated in the motor, with a three-phase supply of 400 V -15 % … 480 V +10 % and PTC thermistor protection. The converter can also be supplied separately, for wall mounting, in several power steps.
What data do I send for a quotation?
The complete order number or a photo of the nameplate, the mains voltage and frequency, the duty (vacuum or pressure) and whether or not a frequency converter is used. When ordering, the lead time is usually 1–4 weeks; we confirm availability and the exact lead time in the quotation.
The page presents data from the 2BH1 300 data sheet (edition 02/2022). For the other sizes in the G-BH1 series, the motor power, order number and the flow and pressure curves are confirmed to you by code; the blower is chosen based on the required flow rate and pressure.
