Precision Airflow,
Zero Oil.

Minimal Upkeep Steps

Everything you actually need to do

• Visual check only — glance at the inlet filter during routine rounds; no teardown needed.
• Clean the filter — rinse or swap the built-in silencer/filter when dust builds, then refit in seconds.
• Sealed bearings — factory-lubricated for life, so greasing schedules simply disappear from your plan.
• Run it and forget it — non-pulsating, low-noise output means stable process air without babysitting.

• Is the blower truly oil-free?

  Yes. The double stage side channel design uses no lubricant inside the air path at all. Because the rotor never contacts metal surfaces during operation, there is nothing to oil, grease or replace over time.

  The discharge stream carries zero oil contamination, which makes these units safe for food packaging, pharmaceutical conveying, medical equipment and clean printing processes where even trace oil would spoil product quality.

• What voltage range does the motor support?

  Tulsi double stage blowers ship configured for standard Indian industrial supply at 220 V single phase or 380 V three phase, both running at 50 Hz frequency across the full power band from 0.4 kW up to 35 HP.

  If your facility runs on different incoming voltage, our engineering team can re-wind or re-specify the motor coil before dispatch so the unit matches your panel exactly — just confirm your supply details when ordering.

• How loud is it compared to standard blowers?

  A built-in silencer sits directly between the impeller and the discharge port, damping pulsation noise that conventional roots-type or lobe blowers produce. Most operators report a noticeable drop in shop-floor sound within hours of installation.

  Because the air delivery is non-pulsating rather than intermittent, there is less vibration through the housing too. That means lower sustained dB readings and a calmer environment for staff working near the machine line.

• Does it require special filters?

  No special filtration is needed for normal operation. Every unit ships with an integrated inlet filter and silencer arrangement already fitted, sized to match the blower's rated airflow.

  For dusty environments such as grain handling, chip extraction or cement plants, we offer optional additional filter housings with larger media area. Ask about upgrading the intake package when you place your order if your site conditions demand it.

• What maintenance schedule should I follow?

  These blowers are engineered for wear-free, maintenance-light operation. There are no bearings in the hot section, no oil changes, no gasket replacements and no timing gears to adjust.

  We recommend only a periodic visual inspection every six months plus cleaning of the inlet filter element. Keep the cooling fan clear of dust and debris and the unit will run reliably for years without intervention.

• Can it handle continuous duty cycles?

  Absolutely. The cast aluminium housing acts as a large heat sink, dissipating compression heat continuously while the external cooling fan keeps the motor winding within safe temperature limits.

  Most customers run their blowers twenty-four seven on bag filling lines, pneumatic conveyors and aeration beds without scheduled downtime. The dynamically balanced rotor prevents thermal fatigue under long shifts.

• Why "double stage" instead of single stage?

  A double stage blower stacks two side channels in series, compressing the air twice before discharge. This yields significantly higher pressure and vacuum capability than a single-stage unit of the same physical size.

  Applications like pneumatic conveying, fluid bed drying and deep tank agitation need that extra pressure head. Choosing double stage means one compact machine replaces what would otherwise require a larger, more expensive compressor.

• What materials go into the housing?

  The main body and impeller are precision-cast aluminium alloy, powder-coated in Tulsi's signature royal blue finish. Aluminium gives excellent strength-to-weight ratio and natural corrosion resistance.

  Internal moving parts use stainless steel shafts and high-grade seals. The combination of light exterior casting with hardened internals delivers durability without adding unnecessary mass to your mounting frame.

• Is the air output pulsating or steady?

  The output is completely non-pulsating. Side channel geometry produces a smooth, continuous column of air rather than the rhythmic pulses typical of piston or diaphragm compressors.

  This matters most in applications like air knife coating, printing registration and component drying where uneven flow causes streaks, misfeeds or inconsistent film thickness. Steady delivery eliminates those defects at source.

• How do I mount the blower safely?

  Each unit comes with four heavy-duty cast mounting feet designed to bolt onto a level steel base plate or existing machine frame using standard M12 fasteners.

  Ensure the surface is flat and rigid enough to absorb vibration transfer. For mobile skid installations we supply optional anti-vibration rubber pads that isolate the blower body from its platform entirely.

• What industries commonly use this model?

  Film scrap collection, automatic bottling, corrugated box packing, plating tank agitation, bulk material handling, chip removal and gas/oil burner systems all rely on this blower family daily.

  Medical and healthcare equipment manufacturers also specify it because the oil-free air meets strict hygiene standards for ventilators, suction modules and laboratory conveyance without downstream purification steps.

• Do you provide spare parts and after-sales service?

  Yes. Tulsi Pumps & Systems stocks replacement inlet filters, silencer elements, coupling components and complete motor assemblies for every model we manufacture.
