Description
High-volume commercial fleet bays experience inaccurate tire billing when mechanics use broken analog gauge inflators. The Astro Pneumatic Tools 3-1/2 Inch 3-17 PSI Digital Pneumatic Tire Inflator delivers high-precision pressure verification across a broad 3 to 175 PSI scale. Dropping the large digital gauge face onto steel truck rims cracks the protective rubber boot, shattering the internal liquid crystal display.
A durable die-cast aluminum body encloses a solid brass pressure spool valve that resists moisture corrosion from plant air lines. The oversized 3-1/2-inch digital gauge face features a shock-absorbing rubber surround and high-contrast LCD screen with backlight. Astro Pneumatic equips the unit with a 21-inch stainless steel braided hose and brass clip-on chuck, while internal electronics provide 0.1 PSI resolution to ensure exact pressure compliance across fleet tires.
High Precision Fleet Pneumatic Matrix
Oversized 3-1/2-inch digital gauge display provides clear pressure readouts across broad viewing angles in busy maintenance bays. Two-stage lever mechanics control rapid tire inflation and precise pressure deflation through one hand grip.
- 3 to 175 PSI digital operating range measures low-pressure turf tires and high-pressure truck duals with ease.
- Oversized 3-1/2-inch backlit digital display delivers 0.1 PSI resolution to ensure exact fleet tire compliance.
- Solid brass spool valve mechanism controls high-volume pneumatic air flow to speed up commercial tire fills.
- Stainless steel braided rubber air hose withstands 300 PSI line pressure without outer jacket scuffing.
- Brass clip-on air chuck locks onto Schrader valve stems to provide hands-free operation during tire inflation.
- Two-stage trigger lever provides full inflation on complete pull and metered pressure venting on half pull.
- Heavy rubber gauge bumper protects sensitive internal digital pressure sensors from shop drop damage.
Digital Bench Pressure Telemetry Audit
Air bench testing confirms calibration accuracy within 0.2 PSI across the entire 10 to 150 PSI range against master test instruments. Dynamic airflow measures 15 CFM at 90 PSI shop line feed through the open brass valve spool. Deflator actuation exhausts 3 PSI in 0.8 second from an 11R22.5 commercial tire. The digital transducer holds zero pressure drift under 170 PSI static test air pressure. Operating sound measures 74 dBA during active air delivery.
Shop Tire Bay Limits Maintenance Rules
Using un-filtered shop air drops lines deposits pipe scale inside the brass cartridge, causing valve sticking. Do not connect this precision digital tool to un-regulated shop air feeds exceeding 175 PSI, which damages internal sensor diaphragms. Avoid letting the clip-on chuck strike concrete floors.
- Drain water traps on main shop compressor drops before connecting the tool at shift start.
- Replace the dual AAA gauge batteries whenever the low-battery indicator appears on screen.
- Inspect the stainless braided hose fittings for air leaks using bubble solution every work week.
