Gardner Denver 2BH1300-1AH16 Side Channel Blower

(Elmo Rietschle / Formerly Siemens Rietschle)

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)

A: Motor construction

H: Standard construction

16: Flange / connection version

⚠️ Note: 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.

📌 Key Specifications (2BH1300-1AH16)

Type: Single impeller, single-stage side channel blower

Rated power: 0.4 kW

Power supply: Single-phase AC220V, 50Hz

Operation mode: Oil-free dry type, no contact or wear inside the pump chamber

Protection class: IP55, Class F insulation

Features: External bearings; bearings are isolated from the air flow chamber, suitable for continuous 24-hour operation

Function: Blow & suction dual purpose, positive pressure air delivery and negative pressure vacuum integrated

Material: Die-cast aluminum alloy pump body, lightweight and corrosion resistant

🛠 Typical Application Scenarios

1. Packaging machinery: Vacuum gripping, suction cup material handling, bag blowing
2. Water treatment: Aeration and oxygen enhancement, small sewage aeration
3. Material conveying: Short-distance pneumatic conveying of fine particles and powder
4. Printing & PCB equipment: Vacuum holding, air drying, air knife
5. Industrial dust removal, waste gas extraction and gas transportation

✅ Product Features

1. Oil-free air delivery: No medium contamination, applicable for food/pharmaceutical industries (with clean filter fitted)
2. Pulsation-free output; no air receiver tank required
3. Low-maintenance design. Original service life up to 20000 hours; only intake filter cleaning periodically required
4. Variable frequency drive supported (0~87Hz speed regulation), adjustable flow and pressure
5. Compact vertical integrated structure, small installation footprint

🔍 Troubleshooting Guide

1. Insufficient pressure / flow: Prioritize checking clogged intake filter, pipeline air leakage and check valve failure
2. Overheat shutdown: Check inlet temperature, overload condition, cooling fan dust accumulation and over-frequency VFD operation
3. Abnormal noise: Bearing wear or foreign object entering pump chamber; stop machine immediately for disassembly inspection
4. Motor overload: High backpressure caused by blocked inlet

📎 Alternative Solutions & Spare Parts

1. Domestic replacement: Domestic 2HB series single-phase ring blower with same specification (0.4kW, single-stage). Matching connection dimensions with slightly different noise and pressure curve
2. Same series upgrade: Three-phase counterpart 2BH1300-7AH16 (0.4kW). Pay attention to power rating difference; cannot directly replace without modification
3. Regular spare parts: Intake air filter, pump chamber O-ring seal, bearing repair kit, vibration isolation pad

📌 Installation & Maintenance Guidelines

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

Ambient temperature: 0~40℃, inlet medium temperature ≤40℃

Long-time closed dead-head operation is prohibited; it may cause overheating and motor burnout

2BH1300-1AH16 (single-phase) cannot directly replace 2BH1300-7AH16 three-phase model due to different power supply and winding

Same suffix (same 16) means identical flange dimension, only motor power supply differs; suffix 06 and 16 flanges are incompatible and pipeline modification required

Brand: Gardner Denver (Elmo Rietschle, Former Siemens G-BH1 Side Channel Blower)

Remarks: 1=Single-phase 220V;7=Three-phase380V;06/16=Flange port;AH=Standard pump body

Supplementary Selection Notes

1. Within 2BH1300 group, pump body and impeller are identical, differences only lie in motor winding and flange port
2. Outer diameter and thread specification differ between port 06 and port16; pipelines cannot be interchanged directly
3. Performance curve: Vacuum and positive pressure are inversely proportional to flow rate. 80m³/h is maximum free delivery flow, maximum differential pressure achieved under closed condition
4. IP55 protection, Class F insulation, continuous 24h operation; inlet medium temperature ≤40℃.

✅ Application Boundary for Model Selection (Important)

Advantages: Single-phase 220V easy site power access; oil-free clean air output; IP55 rated for 24h continuous duty

Limitation: 0.4kW with relatively low pressure, not suitable for high vacuum, long pipeline or high flow applications; designed for small OEM integration. Select high-power three-phase models (2BH1400/1500 series) for large production lines

Model Selection Notes

1. Vacuum application: Air filter must be fitted at inlet to prevent dust entering pump chamber and damaging impeller
2. Positive pressure blowing: Outlet silencer is recommended for noise reduction
3. Medium temperature: Inlet air ≤40℃. Hot, oily or corrosive gas shall not be fed directly into blower

Reference parameters:0.4kW / AC220V single-phase, max flow 80m³/h, max positive pressure130mbar, max vacuum111mbar, blow & suction dual purpose, IP55, single impeller side channel

⚠️ Remark: No fully identical OEM substitute. Classified as [intra-brand replacement, imported competitor equivalent, domestic alternative]. Flange and base mounting dimensions will have minor deviations. Verify port size and mounting hole pitch before replacement.

1. Intra-brand / Group Replacement (Most reliable, identical performance curve)

1. Imported Competitor Equivalents (German Side Channel Blower Brands)

III. Main Domestic Alternatives (Preferred for spare parts cost reduction, widely used for industrial OEM)

✅ Replacement Selection Rules (Important)

1. Match 4 core indicators first: Power supply voltage & phase → rated power → maximum flow → maximum differential pressure. Machine works only if all four match.
2. Condition for direct in-situ replacement: Identical inlet/outlet flange dimension + base mounting hole pitch, no pipe or bracket rework required.
3. Scenarios NOT recommended for domestic replacement: 24/7 continuous operation, high-precision vacuum control, food/pharma clean application and strict low-noise requirement. Keep original Elmo Rietschle blower.
4. 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

1. Flexible vibration bellows for inlet/outlet (compensate flange mismatch, vibration damping & noise reduction)
2. Intake filter assembly matched to new blower port
3. Vibration isolation pads
4. Flange adapter (required for most domestic alternatives)
5. Silencer (optional)

Supplementary: 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.
