Heavy-duty nitrogen generation and controlled inflation deliver consistent tire pressures for cars and vans in a workshop setting. Dual-voltage power options (AC 110V 60Hz and 220V 1PH 60Hz) support common shop electrical supplies and reduce installation complexity. Onboard 70 L storage tank supplies steady flow for sequential inflation and reduces compressor run-time. Adjustable nitrogen purity from 95% to 99.5% and automatic vacuuming before fill maintain gas quality for extended tire life. Integrated pressure sensor and dedicated control chip provide ±1 psi accuracy across a 5–145 psi measurement range with LED readout. Input pressure tolerance up to 10 bar and regulated output below 8 bar accommodate standard passenger and light commercial tires. Simple pipe connection and automatic preset inflation streamline workshop workflow and reduce operator steps. Rugged metal enclosure and modular service access points enable straightforward maintenance in busy garage environments. Designed to operate between −20°C and +70°C and supplied with basic service interfaces for direct integration into existing tire service stations. Backed by a 12-month parts warranty and freight shipping guidance, the unit is suited for commercial garage installation.
