4" 100mm Air Receiver Tank Pressure Gauge | 0-1.6MPa with Green Zone Indicator
Safety-First Air Tank Pressure Monitoring
Our 4-inch (100mm) Air Receiver Tank Pressure Gauge is specifically designed for compressed air systems, featuring intuitive color-coded safety zones for instant status assessment. With a 0-1.6MPa range and dry black steel case, this specialized air tank pressure gauge provides clear visual warning of system conditions. The 3/8" NPT lower mount ensures easy installation on compressor receivers, making it an essential safety component for any compressed air system.
Key Features & Benefits
Instant Safety Assessment: The color-coded dial with green, white, and red zones allows operators to immediately identify safe operating conditions, potential leaks, or dangerous overpressure situations at a single glance.
Optimized for Air Receivers: Specifically configured as an air receiver tank pressure gauge, it provides the range and readability needed for compressor system monitoring.
Durable Dry Construction: The dry black steel case requires no maintenance and performs reliably across a wide temperature range without fluid leakage concerns.
Standard Industrial Mounting: The 3/8" NPT lower mount ensures compatibility with most compressor receiver tanks and industrial fittings.
Clear Zone Definitions:
Green Zone (0.4-1.6MPa): Ideal operating range for stored pressure
White Low Zone (0-0.4MPa): Check for leaks or incomplete pressurization
Red Zone (DANGER): Immediately relieve pressure and investigate cause

Understanding the Color-Coded Safety Zones
This air tank pressure gauge is engineered for immediate visual safety communication:
Zone
Pressure Range
Status
Required Action
White Zone
0-0.4 MPa
Low Pressure
Check for system leaks, verify compressor operation, ensure proper pressurization
Green Zone
0.4-1.6 MPa
Ideal Operating Range
Normal operation--system pressure within safe, stored energy parameters
Red Zone
Above 1.6 MPa
DANGER - Overpressure
IMMEDIATELY relieve pressure, shut down system, investigate cause before resuming operation
Why Every Air Receiver Needs a Properly Zoned Gauge
An air receiver tank pressure gauge is more than just a measuring instrument--it's a critical safety device:
Leak Detection: Pointer consistently in white zone indicates system cannot maintain pressure
Overpressure Prevention: Red zone warning prevents dangerous vessel over-pressurization
Operational Efficiency: Green zone confirms system is operating within design parameters
Maintenance Scheduling: Pressure trends help predict maintenance needs
Typical Applications
Air Compressor Receivers: Primary pressure monitoring on compressor tanks
Industrial Air Systems: Main header pressure indication
Pneumatic Control Systems: Supply pressure verification
Garage & Workshop Compressors: Safety monitoring for service equipment
Manufacturing Facilities: Plant air system pressure status
Installation Safety Notes
Always install with an isolation valve between tank and gauge for safe removal
Use thread sealant appropriate for compressed air service
Position gauge for easy visibility during normal operations
Verify pressure range matches your system's maximum operating pressure
