The 2BH1 series is the classic Side Channel ring blower. Oil-free dry operation, dual function for both positive pressure air supply and negative pressure vacuum suction.
✅ Model Code Explanation
2BH1 300 1 A H 16
2BH1: G-BH1 single-stage side channel blower series
300: Size group
1: Motor version code (1=single-phase; 7=three-phase. Model 2BH1300-7AH16 three-phase version is more common on the market)
O: Motor construction
H: Standard construction
16: Flanşă / connection version
⚠️ Notă: 2BH1300-1AH16 is single-phase 220V; 2BH1300-7AH16 is three-phase 380V. These two models are easily mixed up during model selection, many suppliers incorrectly list 1AH16 and 7AH16 together in product titles.

- Regular spare parts: Intake air filter, pump chamber O-ring seal, bearing repair kit, vibration isolation pad
📌 Installation & Ghid de întreținere
An air filter must be installed at the inlet to prevent dust entering the pump chamber; this is the most critical measure to extend service life
Flexible bellows are recommended at inlet and outlet for vibration isolation and reduce vibration transmission
Temperatura mediului ambiant: 0~40℃, inlet medium temperature ≤40℃
Long-time closed dead-head operation is prohibited; it may cause overheating and motor burnout

- Intra-brand / Group Replacement (Most reliable, identical performance curve)
| Model original | Model de înlocuire | Observații | Difficulty |
| 2BH1300-1AH16 | 2BH1300-7AH16 | Only motor power supply differs, pompa, impeller and flange identical. 7AH16 is three-phase 380V. Pipeline and base can be reused only after power circuit modification | Mediu (Power wiring change) |
| 2BH1300-1AH16 | 2BH1300-1AH06 | Same single-phase 0.4kW with same performance; port flange 06≠16, inlet/outlet size different, pipeline modification needed | Mediu (Pipe adapter required) |
- Imported Competitor Equivalents (German Side Channel Blower Brands)
| Marca | Model echivalent | Matching Points | Diferenţă & Risc | Difficulty |
| Elektror | SD40 (Single-phase220V) | 0.4kW single-stage side channel, close flow and pressure, oil-free blow/suction | Outline and base flange different; base and pipe adapter modification required; slight difference in noise curve | Ridicat, mechanical modification needed |
| SKV-tec | SKV80-S Single-phase version | 80m/h flow, similar pressure differential, equivalent to Rietschle G-BH1 | Mounting dimension not fully matched; mainly for new machine design, retrofit replacement requires base rework | Ridicat |
III. Main Domestic Alternatives (Preferred for spare parts cost reduction, widely used for industrial OEM)
| Domestic Brand | Model echivalent | Descriere | Diferenţă & Risc | Difficulty |
| Full 风 (RB Series) | RB-400AS (Monofazat 220V,0.4kW) | Most common domestic alternative, 0.4kW,80m³/h single-stage ring blower blow & suction | Similar pressure curve; outline, base hole pitch and flange not fully identical, flange adapter required in most cases; noise slightly higher than Rietschle, shorter bearing life. Suitable for vacuum holding, aeration, air drying non-critical applications | Mediu, usually with flange adapter |
| GAORUI | 2RB 400A Single-phase | Matching power, flow and pressure, aluminum pump body, IP54~IP55 | Different base, vibrație mai mare, avantaj evident de pret | Mediu |
| Liongo | 2LG400S | 0.4kW single-phase single-stage ring blower with matching parameters | Pump housing different, inlet/outlet flange to be verified | Mediu |
| Domestic 2HB Series | 2HB1300-1AH16 (Rietschle copy version) | Replicate outline, flange and base dimension of 2BH1300 | High dimensional similarity for direct in-situ replacement. Minor deviation in performance curve; bearing & seal quality vary by grade. Select high-grade bearing version for spare emergency replacement | Scăzut (Recommended for emergency spare replacement) |
✅ Replacement Selection Rules (Important)
- Meci 4 core indicators first: Power supply voltage & phase → rated power → maximum flow → maximum differential pressure. Machine works only if all four match.
- Condition for direct in-situ replacement: Identical inlet/outlet flange dimension + base mounting hole pitch, no pipe or bracket rework required.
- Scenarios NOT recommended for domestic replacement: 24/7 funcţionare continuă, high-precision vacuum control, food/pharma clean application and strict low-noise requirement. Keep original Elmo Rietschle blower.
- Forbid downgrade replacement: Never use 0.25kW model as substitute; insufficient vacuum and flow will cause machine failure.
📌 Auxiliary Spare Parts Recommended to Purchase Together for Cross-Brand Swap
- Flexible vibration bellows for inlet/outlet (compensate flange mismatch, vibration damping & noise reduction)
- Intake filter assembly matched to new blower port
- Vibration isolation pads
- Flange adapter (required for most domestic alternatives)
- Silencer (opțional)
Suplimentar: 60Hz Overseas Application Note
Original model 2BH1300-1AH16 supports 50/60Hz. If replacement model is used for 60Hz overseas project, performance curve under 60Hz must be checked separately; 50Hz parameters cannot be directly adopted.
