Description
Fleet tire maintenance shops suffer costly tire blowouts when un-calibrated analog tire gauges give inaccurate pressure readings. The Astro Pneumatic Tools 7-175 PSI Rechargeable 3.2V Pneumatic Digital Tire Inflator provides certified digital pressure monitoring across wide pressure bands. Slamming shop air line pressure spikes over 200 PSI against the digital sensor chips fractures the silicon diaphragm, locking screen readings permanently.
A durable cast aluminum body encloses a solid brass pressure spool valve that resists moisture corrosion from plant air lines. The digital readout incorporates a 3.2V rechargeable LiFePO4 battery that maintains terminal voltage across cold winter months. Astro Pneumatic equips the tool with a stainless steel braided hose and dual-head chuck, while internal electronic sensors measure line pressure with 0.1 PSI resolution to ensure exact fleet compliance.
Rechargeable Digital Pneumatic Matrix
Integrated rechargeable LiFePO4 battery technology powers high-precision digital pressure sensors without disposable coin cells. Two-position lever mechanics control high-flow inflation and metered pressure deflation through a single hand grip.
- 7 to 175 PSI operating range measures motorcycle, passenger car, and commercial truck tire pressures with ease.
- 0.1 PSI digital display resolution provides laboratory-grade pressure feedback to eliminate fleet tire wear.
- Rechargeable 3.2V LiFePO4 battery holds charge for thousands of cycles without memory fade in cold weather.
- Dual-head straight chuck reaches both inner and outer commercial truck dual wheels without line bending.
- Stainless steel braided air hose withstands 300 PSI working pressure without outer jacket scuffing.
- Two-stage trigger lever controls full air flow on full squeeze and pressure venting on half squeeze.
- Die-cast aluminum handle housing resists structural cracking from continuous drops onto concrete shop floors.
Digital Pneumatic Bench Calibration Audit
Bench testing demonstrates pressure accuracy within 0.5 PSI across the entire 10 to 150 PSI range against a master digital calibrator. Dynamic airflow measures 16 CFM at 90 PSI shop line feed through the open brass valve. Half-squeeze deflator dumps 4 PSI in 0.9 second from a 22.5-inch commercial truck tire. The internal pressure sensor holds zero drift under 160 PSI static test pressure. Sound levels record 73 dBA during active air feed.
Tire Shop Limits Maintenance Directives
Using dirty shop air without inline moisture separators deposits water inside the sensor chamber, shorting digital electronics. Do not submerge this digital inflator in solvent tanks or wash buckets, which destroys the rechargeable battery module. Avoid dropping the digital gauge head onto steel wheel rims.
- Blow water condensation from shop air drops before connecting the inflator at each shift start.
- Recharge the internal 3.2V LiFePO4 battery using the included USB cable once per operating month.
- Inspect the stainless braided hose fittings for air leaks using bubble solution every work week.
Astro Pneumatic Warranty Package Manifest
