Q - More information on Aqus: where can I find it?
A - You can contact the persons indicated on the contacts page or sign up for the periodic newsletter.


Q - Model of brake most suited to my system: does one already exist?
A - To find out, you can send a technical drawing of the tube and the screen head by fax or e-mail, or send a section of tube (not more than 5 cm in length), the associated head and any bushing by post.


Q - “Right-hand” and “left-hand” brakes: why are there two versions?
A
- The location of the brake is always on the opposite side from the return spring. If your product has the spring mounted on the left, a “right-hand” brake is needed, and vice versa.


Q - Brake colour: what does it stand for?
A - Each colour represents a braking force. In decreasing order: white, blue, green, orange.


Q - Brake force (colour): what colour must I use for my screen?
A - White is used for large vertical screens, blue for normal-size vertical, green for large horizontal and orange for normal horizontal ones. Beige for slim cassette with small diameter tubes and low spring load. Violet for very strong spring loads. In any case, a Fandis engineer will be available to help you in choosing the right product.


Q - Insect screen opening speed: how can it be calibrated precisely?
A - To obtain the correct return speed for the pane, just load or release the return spring by a couple of turns and then insert the brake.


Q - Wear: does brake operation undergo changes?
A - The brake has been studied to resist the passage of time intact. Instead, in all insect screens, even those that do not mount a brake, the spring tends to lose force. In this case, all that is needed is to disassemble the system and give the spring a few turns to restore preloading.


Q - Advantages of one-way brake: what are they with respect to a two-way brake?
A - The great convenience of Aqus: it only brakes in one direction, namely that of screen retraction. This means that no additional force is needed to close the insect screen.
