This page shows an example of the ON-LINE calculations of products from the production program of Mandík, a.s., with their full permission to illustrate the calculation together with the product description.

The use of the calculation is very simple:

  1. In the „Values“ section set the desired parameters.
  2. In the table “Selecting the damper size” you will then see the resulting values for all damper sizes.
  3. The contents of this table can be changed by selecting a new quantity in the row of menu buttons below the heading.
  4. The contents of the “Calculated Values” section are updated according to the selected size in the “Flap dimension selection” table.

The MANSEL program for calculating HVAC components

The on-line calculation above on this page contains a sample of fire damper calculations and serves as a presentation sample of our work. We recommend downloading and installing the full version of MANSEL for calculating other HVAC components. MANSEL is designed as a free download for all potential buyers. We created this program upon request by Mandík, a.s., with which we have authorized use of these works as reference material. The program is used for the selection and calculation of air-conditioning components from the production program of Mandík, a.s.

By installing a desktop version of this program, you will receive a version with enhanced functionality, which is not available on our site. For example, these features include:

  • Work with project designs
  • Saving and retrieving selected parts from/to a file
  • Printing

Fire damper FDMA PM description

The copyright for the description of the product belongs to Mandík, a.s.

Fire dampers are shutters in ducts of air-conditioning devices that prevent spreading the fire and combustion products from one fire segment to the other one by means of closing the duct in the points of fire separating constructions. Dampers blade automatically closes air duct using a shutting spring or an actuating mechanism back spring. The shutting spring is started by releasing an initiation lever. The impulse for releasing the lever can be either a manual one, a thermal one or an electromagnetic one. The back spring of the actuating mechanism is started when the thermoelectrical starting mechanism BAT is activated, when a reset button on BAT is pushed or when a power supply of the actuating mechanism is stopped. The damper is sealed with a silicon packing against smoke penetration after closing the blade. At the same time, the damper blade is bedded in a material which enlarges its capacity and air proofs the air duct. Rectangular dampers have two inspection holes. Round dampers have one inspection hole, since the shutting device and the inspection hole can be set into the most advantageous position (with respect to the operation and manipulation with the control device). Dampers FDMA PM are variant of FDMA dampers with blade control out of axis.
