Makita DVP181ZK 4 CFM 18V LXT Vacuum Pump – Tool Only

The Makita DVP181ZK 18V LXT Cordless Vacuum Pump delivers professional-level performance for HVAC technicians needing a portable and reliable vacuum source during A/C installation and service. With a powerful dual-stage oil-sealed rotary vane design, it produces up to 4 CFM (113 L/min) of airflow, capable of evacuating large commercial systems, such as 20 HP refrigeration showcases or office-sized air conditioning units. Compact and cordless, the DVP181ZK is designed to handle demanding jobs without the need for generators or wall power, making it ideal for tight workspaces and remote installations.

Operating on two 18V LXT batteries in parallel (sold separately), the DVP181ZK offers up to 60 minutes of continuous runtime on two 6.0Ah batteries (BL1860B). It features an electromagnetic check valve to prevent oil backflow if the battery runs out mid-job, and a drain port with a shut-off valve for clean, spill-free oil changes. Built-in battery guards protect power packs during tough jobsite use, and an optional shoulder strap attachment improves portability.
