Armed and dangerous, the Simpson ALH4240 has it all - 4,200 PSI and 4GPM flow rates make it a monster of a cleaning machine!

This machine is designed to work daily for the contractor who has jobs to complete and has incredible durability with an aircraft-grade aluminum frame and a 31" pro-style spray wand!
This mean machine will not disappoint for those who need some serious cleaning power and professional, long-lasting power equipment.
