What's included

Four things every order gets.

Matched to duty

Every quote starts from your inlet/outlet pressure, required flow and fluid type. We specify the blower, not the other way around.

Installation & commissioning

Site survey, foundation design, anti-vibration mounting, acoustic hood, electrical tie-in and commissioning handled by one team. Provided on a chargeable basis, separate from blower supply.

Genuine OEM spares

Bearings, seals, oil, filters and gears — supplied genuine. Major rebuild work is routed to OEM-authorised workshops.

AMC bundled

Preventive maintenance and breakdown support can be combined with your pump and genset AMC under a single service contract.

Applications

Where industrial blowers do the work.

Positive-displacement and turbo blowers move air and gas across a wide slice of industry. These are the duties we quote most.

ETP & STP aeration

The biggest use for positive-displacement blowers — supplying diffused air to aeration tanks in effluent (ETP) and sewage (STP) treatment plants. Twin-lobe, tri-lobe and helical screw blowers all serve here; helical screw wins where noise and energy cost matter.

Pneumatic conveying

Moving dry bulk solids — cement, fly ash, flour, plastic granules, lime, food powders — through pipelines in dilute or dense phase. Roots blowers provide the oil-free, steady low-pressure air these systems depend on.

Water & filter backwash

Air scour and filter-bed backwash in water treatment plants, plus tank agitation and channel aeration. Oil-free air keeps the process stream clean.

Aquaculture aeration

Oxygenating fish and shrimp ponds, hatcheries and RAS systems. Continuous, reliable low-pressure air at the flow a pond bank of diffusers needs.

Flotation & agitation

Dissolved-air flotation (DAF), mineral flotation cells and liquid agitation in chemical and process plants — duties that need steady volumetric air, not high pressure.

Biogas & gas boosting

Boosting and transferring biogas, landfill gas and process gases in anaerobic digestion and renewable-gas plants, using gas-duty blowers and compressors.

How we size a blower

Pressure and flow decide the machine — not the badge.

Every blower selection starts from two numbers: the discharge pressure the process needs (set by tank depth, diffuser losses or conveying distance) and the volumetric airflow at your inlet conditions. Get those right and the rest — frame size, motor kW, drive and VFD — follows.

For ETP and STP aeration we work back from tank depth and the oxygen transfer the biology needs; for pneumatic conveying we work from material, conveying rate and line length. Twin-lobe and tri-lobe roots blowers cover most low-pressure duty; helical screw blowers earn their premium on 24×7 plants where energy and noise dominate the lifecycle cost; turbo blowers take over at high flow. We size against your duty point and confirm the model against the OEM catalogue before quoting — never a warehouse pick.

Frequently asked questions

How do I pick between twin-lobe, tri-lobe, helical screw and turbo?

Twin-lobe is the economical workhorse for ETP / low-pressure process air. Tri-lobe cuts noise and pulsation at the same duty. Helical screw is the best choice for urban or noise-sensitive installations at similar pressure. Turbo wins at high flow and medium-to-high pressure where energy cost dominates the lifecycle. We recommend based on your duty point and confirm the model against the OEM catalogue before quoting.

Can you size a blower for my ETP?

Yes. Share the required airflow (Nm³/hr), discharge pressure, inlet conditions, tank depth and runtime — we size for duty point and margin, then specify the motor and VFD.

Do you handle acoustic enclosures?

Yes. Standard acoustic hoods bring blowers to residential-compliant noise levels. We do custom acoustic rooms for very demanding sites (hospitals, hotels).

Are you authorised for Everest Blowers?

Yes — Trading Engineers is an authorised dealer and service partner for Everest Blowers. We supply the full Everest lineup — twin lobe, helical screw, tri-lobe, turbo blowers and vacuum pumps — with genuine spares and factory-backed warranty. Final model is always confirmed against the OEM catalogue.

Can I bundle blower service with pump and genset AMC?

Yes. Trading Engineers runs pump, blower and — via our parent OVN Engineers — generator AMCs. One contract covers all rotating equipment on your site.

What is a roots blower and where is it used?

A roots (twin-lobe) blower is a positive-displacement machine: two figure-of-eight lobes rotate in mesh to trap and push a fixed volume of air each revolution, delivering oil-free low-pressure air. It's the standard choice for ETP/STP aeration, pneumatic conveying, water-treatment air scour and aquaculture — anywhere you need steady airflow at modest pressure rather than high pressure.

What pressure and flow range do these blowers cover?

Positive-displacement (roots and screw) blowers are low-to-medium-pressure machines — typically used up to around 0.5–1 kg/cm² (roughly 500–1000 mbar) on the pressure side, with airflow from a few m³/min up to several hundred m³/min depending on frame size. Turbo blowers extend flow further at similar pressures. We confirm the exact rated envelope for your selected model against the OEM catalogue before quoting.

Twin-lobe vs helical screw blower — which is more energy-efficient?

Helical screw blowers use internal compression and a profiled rotor to cut the energy penalty of straight twin-lobe designs — typically saving meaningful power at the same duty, with lower noise. Twin-lobe still wins on first cost and simplicity. On a plant that runs 24×7, the screw blower's lower running cost usually pays back the price difference; on intermittent duty, twin-lobe is often the better value.

Do you supply blower spares, service kits and overhauls?

Yes — genuine bearings, timing gears, oil seals, air filters, drive belts and complete service kits for the Everest range. Routine servicing and gearbox/rotor overhauls are handled through OEM-authorised workshops so the factory warranty stays intact.
