The SAB 100 is a widely used high-pressure single stage centrifugal blower. The belt drive allows for the selection of the rotation speed, and therefore the actual operating point of the plant, based on the required pressure and flow rate.
Main data
- Pressure up to approx. 180 mbar (18,000 Pa) at 6,000 rpm
- Flow rate up to approx. 1,700 m³/h
- Rotation speed from 2,500 to 6,000 rpm, impeller Ø 500 mm
- Installed power from 0.55 to 15 kW
- Max. inlet fluid temperature: 80 °C (referred to air)
- Flanged ports DN 100 PN 10
- Available in ATEX version for zone 1 and zone 2
Operating Range
Indicative pressure at reduced flow rate, depending on rotation speed:
| Speed [rpm] | Pressure [Pa] | Pressure [mbar] |
|---|---|---|
| 2.500 | ~ 3,100 | ~ 31 |
| 3.000 | ~ 4,500 | ~ 45 |
| 3.500 | ~ 6,100 | ~ 61 |
| 4.000 | ~ 8,000 | ~ 80 |
| 4.500 | ~ 10,100 | ~ 101 |
| 5.000 | ~ 12,500 | ~ 125 |
| 5.500 | ~ 15,100 | ~ 151 |
| 6.000 | ~ 18,000 | ~ 180 |
Construction
- Central body in aluminium
- Aluminium suction and discharge heads, with labyrinth seals on the shaft passage
- Steel impeller keyed onto special steel shaft, statically and dynamically balanced
- Ball and roller bearings in cast iron supports with ring seals; lubrication automatically removes excess grease
- Belt and pulley transmission, with belt stretcher on the motor base
- Transmission protection casing in accordance with accident-prevention regulations
Arrangements
The blower is available with right or left base and with discharge port oriented at 0°, 90° or 270°, in right or left rotation: 8 arrangements to adapt to the plant layout. Indicative dimensions with base: 1,155 × 520 × 820 mm.
Accessories
- Single base for blower/motor in heavy-gauge steel profiles
- Acoustic enclosure: average reduction of approx. 15 dB(A) and protection from atmospheric agents for outdoor installations; double-walled panels with high-density mineral wool
- Suction and discharge silencers
- Suction and/or discharge flexible joints, which isolate vibrations and absorb thermal expansion
Depending on the operating point and environment, the blower can exceed 80 dB(A): for noise-sensitive installations, we recommend an enclosure and silencers.
Applications
- Transport of biogas, pressure gas supply and line boosters
- Gas and oil burners
- Pneumatic transport and centralized dust extraction
- Centralized cleaning, removal of chips and waste
- Air knives, blowing, cooling and drying
- Liquid agitation and water oxygenation
- High vacuum suction for suction cups; blowing and suction in printing machines
- Engine test rooms and spraying systems
