In-House Capability
State-of-the-Art Manufacturing
Our Ajman facility houses everything needed to take a product from raw material to certified finished unit — with zero outsourcing of critical processes.
Precision Winding
Computer-controlled winding machines produce consistent, high-accuracy string wound and melt-blown sediment cartridges.
Ultrasonic Welding
Ultrasonic bonding creates hermetically sealed filter housings — no glue, no leaks, structurally superior to conventional assembly.
Injection Molding
Precision molds produce filter housings, end caps, and fittings in food-grade polypropylene to exact tolerances every cycle.
Quality Testing
Every batch undergoes pressure, flow-rate, and contaminant-reduction testing before leaving the facility.
Filter Cartridges
Precision-Engineered Replacement Cartridges
All cartridges manufactured in-house using premium food-grade media. Compatible with major housing brands and our own NATIONALGREEN systems.
String Wound Cartridges
Depth-filtration sediment removal for particles, dirt, sand, and rust. Graded density construction captures contaminants throughout the media depth.
Melt Blown Spun
Thermally bonded polypropylene fibres form a uniform matrix for consistent particle removal without shedding fibres into the water stream.
GAC Cartridges
Granular Activated Carbon adsorbs chlorine, chloramines, odour, and taste-affecting organics. Large surface area for extended cartridge life.
Carbon Block Cartridges
Extruded carbon block provides superior sub-micron filtration along with chemical reduction — ideal for drinking water and RO pre-treatment stages.
Media Cartridges
Specialty media including KDF, iron reduction, and pH adjustment options. Engineered for specific water chemistry challenges.
