900x130mm concealed Fan coil unit ABS Ventilation wall ceiling grilles Inlet and outlet, Filtration and Maintenance access included

Air ventilation Grilles specially designed for Megawave FCUs, both inlet with access point for maintenance & service,  and outlet for hot or cool air flow. 

• Key Properties of ABS for Ventilation Grilles

  1. Mechanical Strength

     • Tensile strength: 30-50 MPa

     • Impact resistant (especially at low temperatures)

     • Good rigidity while maintaining some flexibility

  2. Thermal Performance

     • Operating range: -25°C to +80°C (short peaks to 100°C)

     • Low thermal conductivity (0.17-0.23 W/m·K)

     • Minimal thermal expansion

  3. Chemical Resistance

     • Resists alkalis, weak acids, and most alcohols

     • Not suitable for strong solvents (acetone, esters)

     • UV-resistant grades available (with carbon black or additives)

  4. Airflow Characteristics

     • Smooth surface finish (Ra 0.8-1.6μm typical)

     • Aerodynamic edge profiles possible

     • Minimal air turbulence generation

  Advantages for Ventilation Grilles

  • Lightweight (1.05-1.07 g/cm³ density) vs metal alternatives

  • Corrosion-proof (ideal for humid environments)

  • Noise reduction (dampens vibration better than metal)

  • Design flexibility (complex shapes via injection molding)

  • Cost-effective for medium-volume production

  Typical Applications

  1. Residential HVAC (registers, diffusers)

  2. Commercial Ceiling Grilles

  3. Fan Coil Unit Covers

  4. Cleanroom Ventilation (static-dissipative grades)

  5. Marine/Coastal Installations (salt-resistant)
