Synthetic Oil: Lobe and Screw Blowers

The Brochure

Lobe and screw blowers operate under demanding conditions—high temperatures, variable pressures, and exposure to corrosive environments. Premature wear, oxidation, and foaming are common culprits behind performance loss and costly shutdowns. Robuschi’s LongLife synthetic lubricants are engineered to counter these risks. With decades of low-pressure system expertise, Robuschi developed a full range of oils tailored to blower-specific needs, ensuring consistent uptime and extended equipment life.

Why LongLife Oil Works

Tailored for Blowers

LongLife oils are formulated specifically for lobe and screw blowers. They cover a viscosity range of ISO 68 and ISO 220, making them suitable for diverse ambient conditions—from sub-zero to high-heat environments.

Performance-Driven Formulation

High oxidative stability extends service intervals
Strong rust and corrosion resistance protects internal components
Low foaming improves operational efficiency
Good demulsibility reduces wear from water contamination
Certified food-grade options available for F&B applications

Temperature-Based Selection

Robuschi provides clear guidance on oil selection based on ambient and discharge temperatures. Oils are categorized into:

Lobe and Screw H Grade: suitable for ambient conditions between +20°C and +45°C.
Screw F Grade: suitable for all approved operating conditions (consult Robuschi).

Each grade is available in multiple volumes (1L, 5L, 20L) with dedicated part numbers for easy ordering.
