Description
Equipment mechanics and fleet crews face flat tire delays across spread-out municipal maintenance yards. The Metabo HPT 18V MultiVolt Cordless Dual Function Inflator delivers 160 PSI high-pressure air alongside rapid high-volume capability. Forcing the high-pressure piston to run non-stop for more than ten minutes without rest causes severe thermal expansion, scuffing the piston sleeve and destroying compression efficiency.
Metabo HPT engineers this dual-function tool with an 18V motor driving both a reciprocating high-pressure piston and a high-flow centrifugal blower. The high-pressure piston rides inside an aluminum cylinder sleeve fitted with an advanced synthetic PTFE cup seal. The dual-path manifold routes air direct through heavy-duty check valves, while internal electronic sensors measure line backpressure to execute automatic motor shutoff at programmed target pressures.
Dual Function Fleet Inflation Matrix
Dual-function pumping architecture handles both high-pressure vehicle tires and high-volume inflatable duct plugs. MultiVolt electronic capability permits operation using 18V batteries, MultiVolt battery packs, or 12V vehicle cigarette lighter cords.
- 18V high-torque motor produces up to 160 PSI to service commercial van, trailer, and tractor tires.
- High-volume air mode outputs high airflow rates to inflate or deflate large equipment baffles in seconds.
- Digital LCD pressure display provides exact target setting and automated shutoff to prevent tire overfill.
- Threaded brass chuck locks onto standard Schrader valve stems to maintain an airtight connection under load.
- Dual-power capability allows operation from 18V MultiVolt batteries or the included 12V vehicle cord.
- On-tool storage bays secure both high-pressure hose and high-volume ducting to prevent vehicle clutter.
- Bright LED work light illuminates dark service locations to improve operator safety along roadside berms.
MultiVolt Spindle Bench Telemetry Audit
Bench load testing demonstrates that the 18V motor draws 8.6 amps continuous while inflating a 225/65R17 tire from 28 to 35 PSI in 1.9 minutes. High-pressure air output maintains 0.52 CFM against 90 PSI backpressure. Compressor head temperature climbs 36 degrees Fahrenheit above ambient during an eight-minute run. Sound emissions record 80 dBA at 1 meter under active high-pressure compression.

Operating the high-pressure mode continuously beyond ten minutes bogs motor speed and risks thermal component damage. Do not purchase this inflator for continuous bead seating on heavy off-road machinery tires, which requires high CFM blast tanks. Never drag the unit by its braided air hose.
- Blow abrasive dust and dirt from motor cooling slots using clean dry air every shift.
- Coat the brass Schrader chuck threads with light machine oil every work week.
- Inspect the 12V vehicle cord plug for terminal corrosion or loose contacts every operating month.
