NTLD: Anti-Drop™ Linear Bar Diffuser
The Anti-Drop™ Linear Bar Diffuser is a linear nozzle made by electrostatically adsorbing a patented CLASS 0 fire-retardant fiber velvet onto the surface of extruded aluminum profiles. Compared to the ELD series (fiber velvet nozzles) , it offers better drip-proof performance and outperforms in environments with significant temperature differences. Customers can replace this nozzle with their existing one at a 1:1 size without additional modifications. The product is tested according to ANSI/ASHRAE Standard 70-06 and has excellent airflow performance and a low noise level (NC). Please contact us for all certifications and test reports.

Border Calculation Formula
- B = Base Size (Meter)
- Assuming a 20mm edge is chosen, the face value is 150mm.
- Neck gauge = 120mm
- Ceiling height = 130mm
- Air vent hole = 125mm
- 16mm edge = meter length - 22mm = inner neck measurement (hole opening = meter length - 15mm)
- 12mm edge = meter reading - 14mm = inner neck measurement (hole = meter reading - 10mm)
| border | Neck | Tianhua left a roar | Wind throat | Neck height |
| 20mm | B-30mm | B-20mm | B-25mm | 20mm |
| 25mm | B-42mm | B-30mm | B-35mm | 20mm |
| 32mm | B-56mm | B-45mm | B-50mm | 32mm |

Frequently Asked Questions
Q: With a 20mm frame and a 150mm vent surface, how many holes should be left in the ceiling?
A: Subtract 26mm from the inner neck (124mm), so a 130mm opening should be left.
(6mm is the thickness reserved for blackening and connecting the bellows material)
