- product specification:
- product category:Assembly Supplies for Refrigeration and Air Conditioning-Pipes-Pipe
- product introduction:The lintel device (for fresh air/ventilation) is a special accessory used in fresh air, central air conditioning, and exhaust systems to "flatten" the round pipe. Its core is to maintain structure, height, and ventilation.
I. Core Role (one sentence)
There is no need to drill holes in the beams or press the ceiling too low, allowing the ventilation duct to pass through the beams safely and smoothly.
II. Resolve 3 pain points
- ? Protecting the building structure
Avoid drilling large holes in load-bearing beams (damaging steel bars/concrete, with safety hazards).
- ? to keep the indoor floor height
The round pipe is flattened (with a thickness of only 3-5cm), which is close to the bottom of the beam. The ceiling does not need to be lowered too much and does not suppress.
- ? ensures smooth ventilation
The internal streamlined transition has low wind resistance, no air leakage, low noise, and does not affect the air volume and effect.
3. Structure and principle
- Appearance: Flat and long "bridge" shape, with round pipes connected at both ends and flat sections in the middle attached to the bottom of the beam.
- Material: ABS engineering plastic/galvanized steel plate, good sealing, deformation resistance, and fire resistance.
- Principle: Round → flat → round variable diameter transition, achieving "circling the beam" without blocking flow or wind.
IV. Application scenarios
- Fresh air system, central air conditioning duct, exhaust duct
-Residential/office/shop scenarios with many beams and limited floor heights
- Renovation plan that does not want to damage the beam body and does not want the ceiling to be too low
V. One-sentence summary
The beam-crossing device = the "bridge-crossing tool" of the pipeline: It is essential for beam protection, floor height protection, ventilation protection, and fresh air/ventilation installation.
