Easy Maintenance Tips for NSRH Roots Blowers That Keep Your Plant Running Smoothly

Roots blowers, like the NSRH series, are widely used by many industrial blower companies in wastewater, chemical, and manufacturing plants. Brands such as Gardner Denver blowers made this technology popular, but long service life always depends on one thing: proper maintenance. Below is a simple, practical guide based on proven industry experience.

Why Maintenance Matters for Roots Blowers

A roots blower looks tough, but it works under constant load. High pressure, long hours, and dusty or chemical environments all add stress.

Good maintenance helps you:

Reduce sudden shutdowns

Keep stable air flow and pressure

Extend bearing and gear life

Lower overall operating cost

For chemical industries especially, small problems can turn into big losses if ignored.

Daily and Weekly Checks You Should Never Skip

Listen and Feel the Blower

A healthy roots blower has a steady sound.
If you hear sharp noise, metal rubbing, or feel strong vibration, stop and inspect.

Check:

Abnormal noise

Vibration level

Motor temperature

Pressure and flow stability

These simple checks take minutes but save hours of repair later.

Keep It Clean

Dust and chemical residue can block cooling paths.
Clean air filters and the blower surface regularly to avoid overheating.

Lubrication: Small Task, Big Impact

Gearbox Oil Management

The gearbox is the heart of the NSRH roots blower.

Maintenance tips:

Check oil level weekly

Change oil on schedule (based on running hours)

Use the correct oil type recommended by the manufacturer

Dirty or low oil is one of the top reasons for gear damage.

Bearing Care

Bearings hate poor lubrication.
Overheating or noise often means lubrication problems or early wear.

Seals, Clearances, and Chemical Environments

Seal Inspection Is Critical

In chemical plants, gas leakage can be dangerous.

Make sure to:

Inspect shaft seals regularly

Replace seals showing wear or corrosion

Watch for oil leaks or gas smell

This is especially important for roots blowers in chemical industries.

Maintain Internal Clearances

Lobe-to-lobe and lobe-to-housing clearances must stay correct.
Never force the blower to run if it is stuck after shutdown.

Managing Wear Parts the Smart Way

Plan, Don’t React

Parts like bearings, belts, and couplings are consumables.

Smart plants:

Keep key spare parts in stock

Replace parts based on condition, not only failure

Record service history for each blower

This approach is common among professional industrial blower companies.

Long-Term Maintenance Strategy

Build a Simple Maintenance Log

Write down:

Running hours

Oil change dates

Abnormal findings

Parts replacement history

Over time, this data helps predict problems before they happen.

Work With Reliable Suppliers

Whether it’s NSRH blowers or Gardner Denver blowers, technical support matters.
Good suppliers help you optimize maintenance, not just sell equipment.

Final Thoughts

Roots blowers are simple machines, but they reward careful attention.
With regular checks, clean lubrication, and planned maintenance, NSRH roots blowers can run smoothly for years—even in harsh chemical environments.

How do you currently maintain your blowers?
Sharing real experiences often helps others avoid costly mistakes.
