Why an AMC pays for itself

A Roots blower in an STP or ETP aeration tank often runs 24×7. When it stops:

Dissolved oxygen falls, biology suffers, and treated water quality can slip out of PCB limits.

Emergency repairs cost more and take longer than planned ones.

A small problem left alone, such as a dry bearing or a choked filter, becomes a timing gear or lobe failure.

An AMC catches these early, for a fixed annual cost you can budget for.

Who it's for

Apartment, hospital, hotel and IT park STPs

Blowers run continuously, and residents notice odour when they stop. See sewage treatment plants.

Textile ETPs and CETPs

In Tiruppur, Erode and Karur, aeration is what keeps you within discharge norms. See textile ETP and ZLD.

Municipal and industrial WTPs

Filter backwash and air scour blowers.

Process plants

Blowers used for pneumatic conveying, combustion air or vacuum.

STP O&M contractors

A reliable blower specialist behind your own team.

Already have blowers we didn't supply?

No problem. Before the AMC starts, we do a one-time condition assessment of each blower. We check readings, inspect noise and vibration, and review the oil and filters. Then we tell you:

Which blowers are in good shape
Which need repair before they can be covered
What a realistic maintenance plan looks like

How to start

Share your blower list

Number of blowers, make and model (nameplate photos) and location.

Site assessment

An engineer inspects each blower and records baseline readings.

Proposal

We recommend a plan with a visit calendar and a fixed annual price.

First visit

We schedule it on the dates agreed in the proposal.

FAQs

AMC Questions, Answered

Coverage, breakdowns, spares and pricing.

Still have a question?

Talk to an engineer about your blowers.

Can you take an AMC on blowers from other suppliers?

Yes. We cover most common makes. We do a condition assessment first so both sides know the starting point.

What happens if a blower breaks down between visits?

AMC customers get priority response. Depending on your plan, call-outs are free or charged at the AMC rate. Parts are quoted separately at your AMC discount.

Does the AMC include spare parts?

Routine consumables are included in the higher plans (see the table above). Major spares such as bearings, timing gears and lobes are quoted when needed, at a discount.

Can the AMC cover pumps as well?

Yes. We can include your multistage and sewage pumps in the same contract.

How is the AMC priced?

By the number and size of blowers, visit frequency, plan level and site location. Share your blower list for a fixed quote.

Do you provide reports for pollution control board inspections?

Our service reports record readings and work done on each visit, so you can show a maintenance history.
