Leybold CLAWVAC CP 300 B – high availability with high pumping speed
The CLAWVAC CP 300 B delivers 295 m³/h at 50 Hz and 347 m³/h at 60 Hz; the ultimate pressure is 140 mbar. The housing measures 1043 × 508 × 631 mm and weighs 304 kg (with IE3 motor); the inlet is G 2" or NPT, the outlet G 1 1/4" or NPT. The operating range of 20 to 60 Hz allows operation with a frequency converter.Wear-free and durable
The pumping chamber works without contact and therefore without wear. Leybold specifies 20,000 operating hours between two oil changes and 48,000 hours until overhaul – this keeps downtime and operating costs low.Typical applications
Central vacuum supply in the food and packaging industry, thermoforming, woodworking (clamping vacuum), plastics processing, degassing and environmental technology.Variants of the CLAWVAC CP 300 B
