Insulated air ducts Isovent 605 series

Description

• Flexible heat-insulated (ISO) and insulated-absorbing (SONO) air duct.
• Spiral frame from high-carbon steel wire.

Features

• 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).
• Especially suitable for applications with requirements to thermal insulation (ISO series) or sound insulation (SONO series) to prevent condensate generation, heat and cold losses and noise level decrease.
• 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.
