NOVUS NV3100PWG is its 212cc 4-stroke OHV horizontal shaft engine, a robust and easy-to-start powerhouse that drives a maintenance-free axial cam pump. This seamless pairing ensures steady, consistent pressure output, delivering an impressive 3100 PSI and 2.5 GPM—enough power to blast away dirt, grime, mildew, and stubborn stains from a wide range of residential surfaces, while remaining gentle enough for delicate cleaning when paired with the right nozzle. The engine is equipped with a 0.79-gallon fuel tank that provides ample runtime for most home cleaning jobs, with a low oil protection system that includes an alarm to prevent engine damage—adding a critical layer of reliability for both new and experienced pressure washer users. A multi-stage shock absorption system further enhances performance, minimizing vibration for smooth, comfortable operation during extended cleaning sessions. https://www.novuspowerequipment.com/gas-pressure-washer-nv3100pwg
