The Paragon P858 Truck Blower is a two-lobe, positive displacement blower engineered specifically for unloading dry bulk road tankers. It features front oil seals that run on coated wear sleeves rather than directly on the shaft, preventing premature oil seal failure and shaft damage, along with a tapered locking mechanism for a more robust timing method. The hydraulic mounting pad is built directly into the machine, and twin drive shafts allow for universal bi-directional mounting. Complete cast iron body and side plate construction, combined with a constant-gap rotor profile, keep operation quiet, while a hidden breather reduces water contamination of the oil. The blower offers drop-in compatibility with other blower models for straightforward upgrades.
