Key Features of Aviation Water Filters
Precision Filtration for Every Application
Drinking Water Safety: Models like 150G-PD and 778000-PD feature 4–5μm filtration with chlorine removal capabilities, eliminating contaminants, particulates, and residual chlorine to meet potable water standards.
High-Pressure System Protection: GL025-1, LX320-1, and GL01150-1 handle pressures up to 15 MPa, protecting liquid cooling and special fluid systems from wear and clogging.
Contamination Indication: GL025-1 includes a differential pressure indicator (0.7±0.05 MPa) to alert crews to filter clogging before performance is affected.
Robust Design for Extreme Aviation Environments
Wide Temperature Tolerance: Operating ranges from -60°C to +120°C (varies by model) ensure reliable performance in unpressurized and temperature-variable aircraft zones.
Lightweight Construction: All models are optimized for minimal weight (as low as 0.44kg for 778000-PD) to meet aircraft weight-reduction goals without sacrificing strength.
Corrosion-Resistant Materials: Stainless steel and aviation-grade aluminum housings resist corrosion from water, moisture, and de-icing fluids, extending service life.
Easy Installation & Maintenance
Standardized Interfaces: Threaded connections (M16×1.5, M20×1.5, 3/8-18NPT) and quick-connect fittings simplify installation in existing aircraft plumbing.
Replaceable Cartridges: Cartridge-style designs (LX320-1, LX340-1, 778000-PD) allow quick filter element replacement without removing the full assembly, reducing maintenance downtime.
Compact Footprint: Low-profile designs fit within limited aircraft plumbing spaces, including the 26mm-long GL01150-1 and the compact SL13-1 filter.
Full Compliance & Customization
Aviation-Grade Quality: All products are manufactured to meet industry standards, with rigorous testing for pressure, flow, and temperature performance.
Custom Solutions: We offer customization for filtration precision (3–150μm), working pressure, interface size, and housing material to match your aircraft's specific requirements.
Applications of Aircraft Water Filters
Aircraft Drinking Water Systems: 150G-PD and 778000-PD filters ensure safe, clean potable water for crew and passengers on commercial and private aircraft.
Liquid Cooling Circuits: GL025-1 filters protect avionics and electronic equipment cooling systems from particulate contamination at high pressures.
Special Fluid Handling: LX320-1 cartridges handle liquid CO₂ and other special fluids in environmental control systems.
General Aviation & Ground Support: SL13-1, GL01100-1, and GL01150-1 serve light aircraft, helicopters, and ground-based aviation water systems.
Replacement Parts: LX340-1 and 778000-PD cartridges provide direct-fit replacements for OEM filter assemblies, reducing maintenance costs.

FAQ - Aviation Water Filters & Cartridges
Q: What's the difference between a complete filter assembly and a replacement cartridge?
A: A filter assembly (like GL025-1 or SL13-1) includes the housing, filter element, and connections for direct installation. A cartridge (like LX320-1 or 778000-PD) is just the replaceable filter element, designed to fit into existing filter housings.
Q: How do I choose the right filtration precision?
A: Filtration precision depends on your application:
Drinking water: 4–5μm with chlorine removal (150G-PD, 778000-PD)
Liquid cooling systems: 3–10μm (SL13-1, GL025-1)
Low-pressure water circuits: 100–150μm (GL01100-1, GL01150-1)
Q: Are your aviation water filters compatible with Boeing/Airbus aircraft?
A: Our filters are designed with standard aviation plumbing connections (NPT, metric threads) and can be customized to match specific aircraft system requirements, including common commercial and general aviation models.
