The turbo blower enclosure is a protective outer casing engineered to ensure that the performance of the high-speed rotating air compressor and internal electrical components remain uncompromised. At NS, we have leveraged years of research and development, along with cutting-edge technology, to create a turbo blower enclosure that delivers both low loss and low noise performance.

Electrical Filter

Harmonic Filter

Harmonic filters are installed at the power input side to eliminate harmonics generated by equipment. They are designed per IEEE-519 Standard (THD-V < 5%, THD-I < 8%)

Harmonic filters can be installed inside the blower enclosure (no additional space needed), or externally if required

They are equipped with a dedicated breaker to prevent reactive power flow under no-load conditions

Benefits of harmonic filter installation:

Improves power quality
Increases transformer and system capacity
Prevents equipment malfunction due to harmonics
Provides noise blocking effect for non-linear loads
Reduces system losses

External installation type

Sine Wave Filter

Sine wave filters convert the inverter’s PWM waveform to a sine wave and are installed on the motor input side to protect the motor

NS sine wave filters are designed to operate at motor speeds up to 60,000 RPM

Benefits of sine wave filter installation:

By applying a sine wave input to the motor, heat generation is reduced and insulation breakdown is prevented.
Reduced motor noise and electromagnetic interference
Improved motor efficiency
Extended motor lifespan
Enables long-distance transmission of inverter output, allowing the motor and inverter to be installed separately in different locations
