PERC 620
With over twice the toxic gas delivery of the PERC 412, H & M Gopher Control introduces the PERC 620 to the expanding custom operator and the large acreage farmer.

Field trials keep two operators busy with the three reels and hoses per side. The higher pressure with a higher cubic feet of gas delivery per minute reduces errors from pulling the probes too fast from mound. The 620 delivers 11.5 cfm per hand probe and hose when all 6 probes are in gopher runs while the 412 deliverers 7.5 cfm when all 4 probes are in gopher runs. That computes to 65 percent more gas per minute put down the hole!!
PERC 620
Standard features like the walking beam tandem axle, the pressurized gas cooling system and the new design for wand holders were developed through a collaboration between H & M Engineering and custom operators with hundreds of hours of field experience with the PERC 412.
With two 1 1/4" intake cooling coils and a 1-1/4" pressure side cooling coil H & M Engineering has solved the excess heat problems created by the 70 cfm pump and the 20 hp motor that drives it.
Separate gas tank, elevated muffler with center line exhaust delivery tubing and a 20 hp Kohler motor give the PERC 620 features that makes it stand apart from the PERC 412 and the PERC 206.
The Champion S60 pump is a 4 cylinder pump in a V configuration. The
combination of the twin V motor and the V4 pump has eliminated much of
the vibration. The motor/compressor combination delivers 70 psi at 50
pounds tank pressure, about two and a half times the gas delivery of
the popular PERC 412.
