Hadron - Model SR Roots Type -Blower & Vacuum

The SR roots type blower is based on an established and robust blower design. The casing is constructed of cast iron and is ribbed to increase the blower’s rigidity and allow for adequate heat dispersal. All rotors are dynamically balanced which reduces vibration, wear and tear on the bearings and eliminates stress fractures on the silencers.

Established Design
Initially designed over 30 years and still successfully used in many applications worldwide

Rotors with carbon/PTFE inserts
Rotor tip insert which minimises the rotor clearances and maximises the airflow efficiency.

Horizontal/Vertical Mounting
Can operate with ports either top to bottom or side to side giving flexibility when fitting to system pipework.

Oil Free Air
Wear-resistant labyrinth seals between the air chamber and lubrication system prevent contamination of the air flow.

Proven Performance
Successfully operating in hundreds of applications worldwide

The SR blowing set package has been designed to achieve optimum performance with maximum efficiency to satisfy customer requirements

The units supply air with volumes ranging from 0 – 10,000m3/h, and pressures up to 1 bar for positive airflow.  For vacuum airflow the units supply air with volumes ranging from 0 – 10,000m3/h, and negative pressures up to -500 mbar

The design ensures the unit takes up minimal floor space suited for applications where space is a critical issue.
