Stihl KOA 20 10.8 Volt 150 PSI Battery-Powered Cordless Inflator (Bare Tool)

Description

Landscaping crews and utility contractors struggle with flat tires on wheelbarrows, commercial mowers, and support trailers. The Stihl KOA 20 10.8 Volt 150 PSI Battery-Powered Cordless Inflator delivers dual-function air delivery from an ultra-compact body. Operating the high-pressure piston non-stop for more than ten minutes without rest causes severe thermal expansion, melting internal check valve seals.

A compact 10.8V motor drives a reciprocating aluminum piston for high-pressure tires and an internal blower wheel for high-volume inflatables. The high-pressure piston rides inside an aluminum cylinder sleeve fitted with an advanced synthetic PTFE cup seal. Stihl isolates the internal pump mechanism using rubber dampening mounts, while a digital sensor monitors line backpressure to execute automatic motor shutoff at programmed target values.

Dual Function Compact Pumping Matrix

Dual-function pumping architecture handles both high-pressure equipment tires and high-volume inflatable water barriers. Integrated rubber feet isolate tool vibration from truck bed surfaces during operation.

• 10.8V motor platform delivers up to 150 PSI high-pressure air to service commercial mower and trailer tires.
• High-volume blower port outputs rapid air flow to inflate or deflate large equipment barriers in seconds.
• Digital LCD pressure screen displays current and target PSI to ensure process repeatability.
• Automatic shutoff control stops motor pumping at pre-selected pressure values to prevent tire blowouts.
• PTFE compression cup seal running in an aluminum cylinder barrel provides oil-free air delivery without bore wear.
• Threaded brass Schrader chuck locks tight onto valve stems to prevent high-pressure connection blow-offs.
• On-tool storage bays secure both high-pressure hose and high-volume ducting to prevent vehicle clutter.

Portable DC Bench Dynamometer Audit

Bench testing indicates the 10.8V motor draws 7.8 amps continuous while inflating a lawn tractor tire from 10 to 20 PSI in 1.4 minutes. High-pressure output delivers 0.38 CFM against 30 PSI backpressure. Cylinder head temperature climbs 32 degrees Fahrenheit above ambient during an eight-minute run. Sound emissions record 79 dBA at 1 meter distance under full compression load.

Grounds Maintenance Safety Service Directives

High-pressure pumping must not exceed ten continuous minutes without allowing a full ten-minute rest period. Do not attempt to use the high-volume blower hose to seat bead rings on vehicle tires, which requires focused high-pressure air streams. Avoid operating the unit on wet muddy ground that clogs bottom vents.

• Blow grass clippings and abrasive dirt from motor cooling slots using dry air every shift.
• Coat the brass Schrader chuck threads with light machine oil every work week.
• Inspect the flexible high-pressure hose for outer jacket abrasion or terminal play every month.
