- Spiral frame from high-carbon steel wire.
|
- Pollution-free, no harmful substances emission during operation.
- No chlorine and cadmium content.
- High elasticity and temperature resistance: short-time resistance up to +250°С for M0, short-tome resistance up to +150°С for M1).
- High rupture and mechanical resisting features.
|
RECOMMENDED APPLICATION |
- Applied in residential and industrial ventilation, air conditioning and heating systems, peripheral sections of large central utility systems with the maximum pressure 3000 Pa and special fire-resistance requirements to air ducts (M0 or M1 models).
- Recommended for ventilation of child care centres, educational and medial facilities, spa resorts.

PRESSURE LOSS DIAGRAM PER 1 M STRETCHED AIR DUCT |
CALCULATION EXAMPLE: |

|

- Select a curve that matches the air duct diameter [mm], 200 mm in this case.
- Find the intersection point of this line with the vertical line of the required air flow in m3/h, 500 m3/h in this case.
- The horizontal line that shows the pressure loss in Pa per 1 m straight air duct crosses this intersection point.
- Multiply pressure loss value (2.4 Pa/m at 20°С) by total air duct length to get the total pressure loss value. To calculate pressure loss in case of bends consider each bend as extra air duct meter.
