Amphi-Vent®

Protects drinking water

Amphi-Vent® improves the long-term quality of drinking water

Amphi-Vent® is a ventilation housing with air filter for mounting on drinking water reservoirs to effectively filter incoming air and prevent pollen, combustion products and other air pollutants from entering the reservoir and affecting water quality.


Amphi-Vent® is available in two different variants adapted for indoor use and outdoor use, respectively. It is also available in two different sizes. Amphi-Vent® 125 and Amphi-Vent® 200.


The filter device is equipped with a pressure fuse which consists of a diaphragm which releases if the reservoir is emptied of water in the event of a sudden emptying due to, for example, a pipe rupture and the building structure is exposed to a large negative pressure.


The air filters for Amphi-Vent® are available in two different filter classes, F7 fine filters and H13 hepa filters. The air filters are tested according to EN779 and EN1822 respectively. Six months after installation of Amphi-Vent®, the degree of clogging of the air filters should be assessed.

Amphi-Vent

Amphi-Vent® is an effective filter for the air that needs to be supplied when the water level drops in the reservoir

Air filters are checked 1-2 times a year to see how clogged they are. If there is a lot of air pollution or pollen in an air filter, it is replaced with a new one because the flow of air is limited if it is too clogged. Air filters older than two years are recommended to be replaced for hygienic reasons and replaced with new air filters.


When checking the air filter, the pressure fuse should also be checked so that it is complete. If the pressure fuse is not complete, the air entering the reservoir will not be filtered. Broken or broken pressure fuse should not be repaired but should be replaced and replaced with a new pressure fuse.


Heater

If there is a risk of ice formation in the air filter, a filter heater can be mounted in the filter housing. Ice formation in the air filter means that the ventilation of the reservoir does not work properly and with filter heaters the risk of ice formation is minimized. The filter heater is ordered and delivered as an option and optional equipment and can also be retrofitted to already installed air filters.


The filter heater is a product specially developed by Amphi-tech® AB. Note that special attention must be paid to the reservoir and its air supply in weather conditions that can cause frost formation. In case of risk of icing in the ventilation pipes, special frost protection or electronic vacuum relief type Amphi-Vac bör should be considered.

Product Sheet

Technical data

Amphi-Vent® meets the requirements of SS-EN 1508. Patent number: 525 509


Amphi-Vent® filter housing

Available for outdoor and indoor installation. The number designation corresponds to the pipe size.


For outdoor installation (stainless steel solid construction, available in acid-proof):

Amphi-Vent® 200u

Amphi-Vent® 125u

Can be mounted on existing ventilation and goosenecks.


For indoor installation (stainless, acid-proof):

Amphi-Vent® 200i

Amphi-Vent® 125i

Filter insert

The filter is made of moisture-resistant material with a filter cloth carefully selected to minimize microbial growth. The filter is available in filter class F7 (fine filter, EN779) and H 13 (microfilter, HEPA). Filter class F7 has a particle separation rate of over 80%, this means that, for example, pollen, plant spores, mold and particles of bacterial size can be filtered out. Filter class H 13 has a particle separation rate of 99.95%, which means that it can separate, for example, viruses and radioactive dust particles.


Vacuum protection

The vacuum fuse consists of a diaphragm that trips at a negative pressure of -3500 Pa. Safe operation, without mechanical parts.



For pressure-sensitive tanks and reservoirs, active negative pressure protection with Amphi-Vac ™ is recommended.
