Insulated air ducts Isovent N series

Description

• Flexible insulated air duct from metalized polyether film.
• Spiral frame from high-carbon steel wire.

Features

• Pollution-free flexible air duct insulated with mineral wool layer.
• No harmful products emission during operation.
• No chlorine and cadmium content.
• High elasticity and temperature resistance: short-time resistance up to +120°С.

Recommended application

• Applied in residential and industrial ventilation, air conditioning and heating systems with special flammability and temperature resisting requirements, in particular for applications with the need of heat insulation combined with flexible air ducts to prevent condensate generation and heat and cold losses as well as in peripheral sections of large central utility systems with the maximum pressure 3000 Pa.
• Recommended for ventilation of child care centres, educational and medial facilities, spa resorts.

Pressure loss diagram per 1 m stretched air duct

Calculation example:

1. Select a curve that matches the air duct diameter [mm], 200 mm in this case.
2. 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.
3. The horizontal line that shows the pressure loss in Pa per 1 m straight air duct crosses this intersection point.
4. 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.
