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.

Synthetic Oil: Lobe and Screw Blowers

Why LongLife Oil Works

Tailored for Blowers 

LongLife oils are formulated specifically for lobe and screw blowers. They cover a wide viscosity range (ISO 100–320), 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:

  • H Grade: >130°C discharge
  • M Grade: 100–130°C
  • C Grade: <100°C
  • F/GX Grades: For forced lubrication or specific operating conditions (consult Robuschi)

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

FAQs

While both use synthetic formulations, the viscosity and thermal stability requirements differ. Robuschi offers separate product lines for each, optimized for their mechanical and thermal profiles.
