Description
Field mechanics face dead batteries and limited power outlets when inflating service truck tires on remote highway jobsites. The DEWALT 20V MAX* Cordless Tire Inflator bare tool with 120V power adapter delivers 160 PSI pressure from triple-power source options. Pushing the high-pressure mode beyond its 15-minute duty cycle without rest overheats the compressor head, cooking internal piston seals under continuous load.
A high-output 20V motor drives dual internal pump mechanisms: a reciprocating high-pressure piston for tires and a high-volume centrifugal blower for large inflatable gear. The high-pressure piston utilizes a durable PTFE cup seal operating inside a precision-honed aluminum cylinder. DEWALT encloses the dual pump stages within a rugged polymer roll cage, while the separate N557514 AC power supply converts standard 120V wall power into continuous DC current.
Triple Power High Pressure Matrix
Triple power source flexibility allows operation from 20V lithium batteries, 12V vehicle DC ports, or 120V AC wall outlets. High-pressure and high-volume modes divide mechanical duties to optimize air delivery across varied applications.
- High-pressure pump mode delivers up to 160 PSI to service commercial van, truck, and trailer tires.
- High-volume blower mode outputs rapid air flow to inflate or deflate large equipment barriers and bladders.
- Digital gauge display incorporates automatic shutoff at target PSI to prevent over-inflation damage.
- All-brass threaded chuck attaches secure to Schrader valve stems to prevent accidental disengagement.
- 120V AC power adapter connects direct to wall outlets to provide limitless runtime in garage stalls.
- Dual-mode hose routing stores both high-pressure and high-volume hoses flush inside tool body channels.
- Integrated LED work light illuminates dark wheel wells and nighttime roadside breakdown locations.
Dual Pump Bench Dynamometer Audit
Bench testing shows the high-pressure stage draws 8.8 amps on 20V power while inflating a 235/65R17 tire from 30 to 40 PSI in 1.8 minutes. High-pressure output delivers 0.55 CFM against 90 PSI backpressure. Cylinder head temperature climbs 38 degrees Fahrenheit over ambient during a 12-minute run. Sound levels measure 80 dBA on high-pressure mode and 74 dBA on high-volume mode at 1 meter distance.
Roadside Service Limits Maintenance Directives
High-pressure runs must not exceed 15 continuous minutes without allowing a full 15-minute cooldown 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. Keep the AC power adapter dry during wet roadside rain events.
- Blow dirt and road grime from air intake louvers using dry shop air every shift.
- Coat the brass Schrader chuck threads with light machine oil every work week.
- Inspect the 120V power adapter cord for cuts or strain boot tears every operating month.
