Katool KT-N80 – Nitrogen Tire Inflator (Automatic, 4-Tire)
Katool KT-N80 Tire Nitrogen Generator - Professional Automatic Inflation System
The Katool KT-N80 is a fixed-location, shop-grade tire nitrogen generator designed for passenger cars and light vans. It connects to your existing compressed air supply, automatically separates and stores nitrogen in a 70-liter internal tank, and inflates up to four tires simultaneously to a pre-set pressure with adjustable high-purity nitrogen (95-99.5%).
Also known as: AK-N80, AT-N80 (regional variants with identical specifications)
Key Features & Benefits
Adjustable High-Purity Nitrogen Generation
The unit delivers nitrogen purity ranging from 95% to 99.5%, allowing you to adjust purity levels based on your service requirements. This engineering flexibility means you can balance inflation speed with nitrogen quality without requiring multiple machines.
Shops often need to structure tiered nitrogen services or respond to different vehicle requirements without investing in separate systems. This adjustable approach addresses that industry-wide challenge by delivering one machine that handles multiple purity scenarios.
This enables shops to offer both standard and premium nitrogen services from a single system, improving equipment utilization and service flexibility while reducing capital equipment costs.
Four-Tire Simultaneous Inflation with Automatic Vacuum
The system inflates up to four tires at once through a multi-hose manifold with quick-connect fittings, each independently controlled to a pre-set pressure. The automatic vacuum-and-fill cycle removes residual air from new or converted tires, ensuring high internal nitrogen purity on the first cycle.
Converting air-filled tires or handling newly mounted wheels traditionally requires manual pre-inflation steps and careful technician monitoring. The automatic vacuum cycle addresses this by removing the guesswork and streamlining first-time nitrogen conversions.
This eliminates manual inflation steps and reduces technician error during tire conversions. The 0-pressure tire mode handles flat or newly mounted wheels without requiring manual pre-filling, speeding up service cycles and improving consistency.
Low Power Draw with Dual-Voltage Support
The unit consumes just 30 W of electrical power and supports both 110 V 60 Hz and 220 V 1PH 60 Hz single-phase configurations. This low-draw design eliminates the need for dedicated high-amperage circuits and reduces operating costs significantly.
Many shops lack dedicated high-capacity electrical circuits and cannot accommodate equipment requiring 100+ watts of continuous power draw. The KT-N80's dual-voltage design addresses regional power infrastructure variations while keeping electrical complexity minimal.
This enables shops in different geographic regions to operate the unit with standard wall outlets, reducing installation complexity and operating expense. The low power consumption means the unit runs cost-effectively alongside other shop equipment without straining facility electrical systems.
Compact Vertical Cabinet with Integrated Storage Tank
The system features a 70-liter integrated nitrogen storage tank housed within a vertical cabinet mounted on heavy-duty casters. The tall, narrow footprint keeps floor space comparable to a standard tool cabinet while providing meaningful nitrogen buffer capacity.
Small and mid-sized shops often cannot justify large multi-tower nitrogen systems that occupy significant floor space and require dedicated power infrastructure. This compact form factor addresses that constraint by delivering professional-grade nitrogen storage without warehouse-scale equipment.
This enables shops to add nitrogen services to existing bays without relocating equipment or restructuring work areas. The caster-mounted design allows repositioning as facility needs change, providing operational flexibility that fixed tower systems cannot offer.
Automatic Chip Control with Precise Pressure Sensors
The LED digital display interfaces with a dedicated microprocessor that manages the inflation cycle, monitors target pressures, and controls the automatic shutoff when pre-set pressure is reached. Precision pressure sensors deliver ±1 psi accuracy across the entire 5-145 psi measurement range.
Manual pressure gauges and traditional inflation controllers are prone to technician error and inconsistent results, particularly when managing multiple tires simultaneously. The chip control system addresses this by automating the decision points and removing subjectivity from the inflation process.
This improves inflation consistency and reliability compared to manual methods, reducing pressure-related complaints and repeat visits. The automatic shutoff prevents over-pressurization, protecting customer tires and reducing warranty claims from pressure-related issues.
Broad Operating Temperature Range
The unit operates safely across a -20°C to +70°C temperature range (-4°F to 158°F), supporting use in climate-controlled shops, unheated winter garages, and hot regional environments without performance degradation.
Traditional nitrogen systems often suffer reduced performance or require specialized climate control to maintain reliability. The KT-N80's extended temperature range addresses the need to operate in diverse facility environments without additional infrastructure investment.
This enables reliable operation in basements, outdoor service bays, and facilities without sophisticated HVAC systems. Shops in colder or hotter climates can deploy the system year-round without worrying about seasonal performance changes.
Applications & Use Cases
- Tire Shops & Auto Repair Garages: Add nitrogen inflation as a premium service for passenger vehicle tire maintenance, extending tire life and improving fuel efficiency with consistent pressure maintenance.
- Dealership Service & PDI Centers: Deliver high-purity nitrogen for new vehicle pre-delivery inspection routines, ensuring customer vehicles meet quality standards with properly inflated tires before handoff.
- Light Vehicle Fleets: Maintain delivery vans, service vehicles, and company automobiles with consistent high-purity nitrogen, reducing oxidation and tire pressure degradation over extended service intervals.
- General-Purpose Garages: Deploy a compact nitrogen solution without justifying large multi-tower systems, serving garages that handle mixed services and want to offer nitrogen without major capital investment.
