Overview
The Harben Pro 4000 Drain Jetter Van Pack is a high-capacity, van-mounted drain-cleaning system built for professional contractors working larger drains up to 300 mm diameter. Powered by a 50 hp Stage 5 low-emission diesel engine and the proven Harben run-dry diaphragm pump, it offers selectable performance up to 6,000 psi (415 bar) — 4,000 psi / 12 gpm, 5,000 psi / 9 gpm or 6,000 psi / 7 gpm.
A 500-litre non-corroding plastic tank and a pivot-mounted reel carrying 100 m of 1/2" hose keep it working for longer between refills. The Jump Jet system extends reach on runs up to 200 m, with an anti-freeze kit, integrated hose speed control and radio or manual control up to 100 m.
