NLB7420B Stack Cleaner

NLB SpinJet® stack cleaning seals combine the force of high-pressure water with various nozzle offset angles to clean stacks and large pipes more efficiently than any other method. The seal features a built-in magnetic brake for adjustable rotational speed, which helps provide the most efficient combination of pressure, flow, rotation speed and rate of travel.

The NLB7420B operates at pressures up to 10,000 psi (700 bar) and flows to 25 gpm (95 lpm). The NLB7420B-20K operates at pressures up to 20,000 psi (1,400 bar) and flows to 16 gpm (61 lpm). And the NLB7420B-40K operates at pressures up to 40,000 psi (2,800 bar) and flows to 20 gpm (76 lpm).
