Based on the specifications you provided (5kW, Stainless Steel, High-Pressure), this is a heavy-duty industrial blower typically used for demanding pneumatic conveying, wastewater aeration, or chemical exhaust systems.
Here is a detailed breakdown of what this machine likely entails, typical specifications, applications, and key considerations.
Likely Type of Blower
Given the combination of 5 kW (25 HP) and Stainless Steel, this is most likely a Regenerative Blower (Side Channel Blower) or a Multi-Stage Centrifugal Blower, built with corrosion-resistant materials.
Typical Technical Specifications
| Parameter | Typical Value |
|---|---|
| Power | 5 kW (25 HP) |
| Voltage | 400V / 690V (3-Phase, 50/60 Hz) |
| Max Airflow | ~600 – 1,200 m³/h (350 – 700 CFM) |
| Max Pressure | ~250 – 650 mbar (100 – 260 inH₂O) |
| Max Vacuum | ~250 – 600 mbar (100 – 240 inH₂O) |
| Material | SS304 or SS316L (Casing & Impeller) |
| Noise Level | ~70 – 80 dB(A) (with silencer) |
Key Advantages of Stainless Steel Construction
- Corrosion Resistance: Essential for handling aggressive gases (acid fumes, chlorine, salt-laden air) or hot, moist air.
- Hygiene: Suitable for food processing, pharmaceuticals, and clean rooms (prevents rust contamination).
- High Temperature Tolerance: Can often handle air/gas temperatures up to 250°C–300°C (depending on seals).
Common Applications
- Wastewater Treatment: Aeration in sewage treatment plants (where H₂S and moisture are present).
- Pneumatic Conveying: Transporting granular or powdered materials (cement, flour, plastic pellets).
- Chemical Processing: Fume extraction, vapor recovery, and tank agitation.
- Food & Beverage: Drying, vacuum packing, and conveying of food products.
- Environmental Remediation: Soil vapor extraction (SVE) systems.
Manufacturer Examples (if searching for a specific unit)
- FPZ (Italy): SCL Series (AISI 304)
- Busch (Germany): R5 series (special materials) or Samos series
- Airtech (Italy): HST Series
- Elmo Rietschle: V-VT Series
- Dargang (China): High-End Regenerative Blowers
- Puma (Taiwan): Stainless Steel series
Critical Purchasing Considerations
Before buying, verify these specific details:
- Stainless Steel Grade: 304 (standard corrosion resistance) vs. 316L (superior for chlorides/acids). This drastically affects price.
- Shaft Seal Material: PTFE (for high temp) or Viton (for chemical resistance) vs. standard NBR rubber.
- Motor Protection Class: IP55 (dust/water jets) or IP65 (washdown environment).
- Voltage: Confirm if it requires a Star-Delta starter or VFD (Variable Frequency Drive) for soft start and speed control (18.5 kW motors are typically direct-on-line only with a suitable starter).
- Weight: An 18.5 kW stainless steel blower is heavy (likely 250–400 kg). Ensure mounting structure is reinforced.
Operational Notes
- Noise: Even with silencers, this power level is loud. Ear protection is recommended for nearby personnel.
- Heat Generation: The high internal compression generates significant heat. Ensure adequate cooling air flow around the blower.
- Maintenance: Check bearings and V-belts (if applicable) regularly. Stainless steel construction should only require mild cleaning.
