Keep Your NSRH Roots Blower Running Smoothly: Simple Tips for Better Lubrication

Why Lubrication Matters More Than You Think

NSRH Roots blowers are known for their stable airflow, low noise, and long service life. But no matter how well they’re built, they still rely heavily on proper lubrication. Without the right oil and the right habits, even the best blower can lose efficiency, make noise, or wear out too fast.

What Makes NSRH Different?

The NSRH series uses a high-precision rotor design and a rigid bearing system. These parts move fast, handle heavy loads, and face long working hours—so they need clean, high-quality oil at all times.

Pick the Right Oil From the Start

Not all oils work for Roots blowers. NSRH blowers perform best with specialized oil designed to handle heat, oxidation, and heavy friction.

The Big Mistake to Avoid

Many users think industrial gear oil is “close enough.”
It’s not.
Using the wrong oil can increase wear, raise temperature, or even damage gears over time.

How to Add and Change Oil the Right Way

Adding oil looks simple, but doing it wrong creates problems later.

Before You Add Oil

Always stop the blower

Wait until it cools down to room temperature

Add oil only to the required level—never too much or too little

When to Change Oil

Oil age depends on temperature, workload, and hours of operation. A blower in a hot or dusty place needs more frequent oil changes. Fresh oil keeps gears smooth, protects bearings, and saves energy.

Clean Oil = Longer Blower Life

One of the easiest ways to protect your NSRH blower is to keep the oil clean.

Simple Maintenance Habits

Clean the oil tank and filter regularly

Keep moisture and dust out of the system

Check for leaks around seals and joints

If the oil gets cloudy, dark, or watery—change it. Don’t wait for the blower to start acting strange.

Take It a Step Further With Smart Monitoring

Many factories are now adding simple monitoring tools to their NSRH blowers. This doesn’t require a full “smart factory”—just a few sensors.

Useful Add-Ons

Oil temperature sensors help detect overload or friction

Oil pressure sensors warn you when lubrication isn’t flowing right

Oil circulation filters keep oil clean for a much longer time

A few small upgrades can cut down failures and extend the blower’s life by years.

Tips for Different Working Conditions

Wet and Humid Areas (Like Wastewater Plants)

Moisture can enter the oil easily—shorten the oil-change cycle.

Dusty Places (Like Pneumatic Conveying)

Use stronger filtration and check oil cleanliness more often.

Final Thoughts

Taking care of lubrication doesn’t need to be complicated. With the right oil, timely maintenance, and a few smart upgrades, your NSRH Roots blower can stay efficient, stable, and reliable for a long time. A little attention today prevents breakdowns tomorrow.
