1 IN-LINE MIXED FLOW DUCT FANS MIXVENT-TD Fan Systems MIXVENT TD / MIXVENT TD-T MIXVENT TDx2 ACCESSORIES Description Range Construction The MIXVENT system has been designed to compliment the MIXVENT-TD range of in-line fans. All MIXVENT TD fans include the combination of a powerful motor factory matched to a mixed flow impeller. This motor and impeller combination enables the MIXVENT- TD fans to deliver high airflow performances with the minimum of noise generation against high static pressures typically found in ducted ventilation systems. The unique design of the MIXVENT TD and TDx2 support brackets, allows the motor and Classic centrifugal In-line centrifugal MIXVENT flow impeller assembly to be fitted or removed without dismantling the adjacent ducting and therefore facilitating any installation or maintenance. The internal aerodynamic design of MIXVENT- TD fan enables the unit to generate large air volumes and pressures with the minimum of in-duct or radiated noise. An additional advantage of the MIXVENT TD fans is that they are fitted with direct connection two speed motors as standard. In addition, all motors are suitable for speed control regulation using electronic or auto-transformer controllers. The MIXVENT-TD fans offer the ideal in-line duct fan solution for a wide range of HVAC ventilation applications. The MIXVENT system includes 3 ranges of products: MIXVENT TD, Single Fan Unit MIXVENT TDx2, Twin Fan Unit MIXVENT TD-T, Twin Fan Unit with Overrun Timer The MIXVENT-TD consists of eight (8) nominal sized in-line fans. All models are specifically designed for direct connection in-line with industry standard diameter circular ducting. The MIXVENT-TDx2 range consists of two MIXVENT TD fans mounted in series to produce almost twice the pressure of a single TD fan. The range consists of 5 nominal fan diameter sizes. The MIXVENT-TD-T consists of a range of five (5) nominal size TD fans (16, 25, 35, 5 and 8) fitted with an Run-On-Timer adjustable between 1 to 3 minutes. (The MIXVENT TD-T range is not suitable for speed control.) Accessories The MIXVENT System includes a specific range of accessories enabling the installation of different combinations of the MIXVENT TD and MIXVENT TDx2 fans, using models 35, 5, 8 and 1. These combinations include: MIXVENT Twin Two MIXVENT TD fans mounted in parallel using the Twin Base Kit. Mounting the fans in parallel produces double the duty of one fan (at the same pressure). MIXVENT Twin x 2 Two MIXVENT TDx2 fans mounted in parallel using the Twin Base Kit. Mounting the fans in parallel produces double the duty of a single TDx2fan (at the same pressure). MIXVENT Twin x 3 MIXVENT-TD and MIXVENT TDx2 mounted in series using the Flange (MBR). The pressure achieved by this arrangement will produce almost three times that of a single unit (at the same ar volume). To compliment the MIXVENT System a range of electrical and additional mechanical accessories are available to complete the most demanding installations. 29 The MIXVENT TD models are manufactured in tough reinforced plastic, except models 16, 1, 13 & 2 which have a metal casing and are finished in a tough epoxy-polyester paint coating. The TD fan duct connection flanges are manufactured from reinforced plastic, except for models 8, 1, 13 & 2 which are constructed from epoxy-polyester coated metal. Impellers The impeller blades are moulded in tough ABS plastic except models 8N, 1, 13 and 2 which are in metal. Motors Models 16, 25 and 35: Single-phase, 23V 5Hz, shaded pole induction asynchronous motor in die cast aluminium. All motors include direct two speed connection and are also suitable for voltage speed control*. Manufactured in accordance to standards UNE and CEI Class ll electrical insulation (model 16) and Class l (models 25 and 35) IP 44 Protection Class B Motor Insulation Safety Thermal Overload Protection (fuse type) Self-lubricating sleeve bearings. Models 5, 8, 1, 13 and 2: Single-phase induction asynchronous motor, with permanent capacitor and external rotor in die cast aluminium. All models include direct two speed connection and are also suitable for voltage speed control*. Manufactured in accordance with standards UNE and CEI Class I electrical insulation.
