How to Save Big on Energy with Your LT 200 Roots Blower

Electricity prices are hitting new highs in 2026 and everyone is looking for ways to cut costs. If you use an LT 200 Roots Blower in your factory or farm, you already know it is a workhorse. However, even a strong machine can be a money pit if it is not running efficiently. The truth is that many operators are paying 20 percent more than they should on power bills because of small setup errors.

The good news is that you do not need to buy a brand new system to fix this. You can make your LT 200 much greener and cheaper to run by following a few grounded and practical steps that focus on how the air actually moves through your system.

1. Stop Fighting Backpressure in Your Pipes

One of the most common reasons for high power bills is a poorly designed pipe layout. If your pipes are too small or have too many sharp turns, your LT 200 has to work twice as hard to push the same amount of air. This is what we call backpressure and it is a silent energy thief that creates unnecessary heat.

Make the Air Flow Smoothly

You should check your discharge lines for any sharp 90 degree elbows. If you replace these with long radius bends, the air flows much more naturally. This simple change reduces the friction in the system and lowers the load on your motor. When the motor does not have to fight the resistance of the pipes, it consumes significantly less electricity every hour of operation.

2. Use a VFD to Control Your Speed

Many people run their LT 200 at full speed all day and all night. But does your process really need maximum air every single minute? Running at a constant 100 percent speed when you only need 60 percent is like driving a car at full throttle while keeping your foot on the brake. It wastes money and wears out your bearings faster.

Adjust the Air to Your Real Needs

By installing a Variable Frequency Drive or VFD, you can slow the motor down during times when air demand is low. For example, in wastewater treatment plants or large scale fish farming, oxygen needs change throughout the day. Slowing down the RPM of your LT 200 even a little bit can lead to massive energy savings over a month. It also makes your workspace much quieter which is a great bonus for your team.

3. Better Maintenance Means Better Efficiency

Friction is the enemy of efficiency in any mechanical system. If the internal parts of your blower are struggling to turn, they will pull more current from the power grid. This often happens because of old gear oil or clogged intake filters that restrict the air.

Keep It Clean and Slippery

You should switch to high quality synthetic gear oil because it stays slippery even when the LT 200 gets hot during long shifts. Also, do not forget the intake filters. A dirty filter is like trying to breathe through a thick cloth while running. It forces the blower to suck harder, which wastes energy. Cleaning your filters every few weeks is perhaps the cheapest energy saving hack available today.

4. Check Your Belts and Alignment

Finally, take a quick look at your drive belts. A belt that is slightly loose or misaligned will slip and create heat instead of moving the rotors. If you hear a squealing noise when the machine starts, you are literally throwing money into the air. Keeping the belts at the right tension ensures that every bit of power from the motor goes directly into moving air for your project.
