Which accessories does a pool or jacuzzi blower need?
- Intake filter: keeps dust from the surroundings out of the bath water
- Pressure relief or limiting valve: blows off at excessive counterpressure, for instance a full bath or covered holes
- Check valve: prevents water running back into the blower through the pipework
- Silencer or acoustic enclosure: limits noise on start-up and during operation
- Which blower do I need for a jacuzzi or bubble bench?
"
DOVAC calculates the blower. The following details are needed:
| Detail | Example |
|---|
| Number of people or bath dimensions | 8 people is about 7 m of seating perimeter |
| Number and diameter of the air holes | Around 3 mm, often in two rows in the pipework |
| Water depth, and therefore counterpressure | 80 cm to 1 m for a jacuzzi |
| Distance to the plant room | A long pipe run needs a different blower than 3 m |
Without this calculation there is too little bubble formation as soon as the bath is full.

- What goes wrong with an incorrectly selected blower?
"
- Barely any bubbles as soon as several people are in the bath
- Wave action instead of fine bubbles at an incorrect operating point
- A burnt-out blower from excessive counterpressure when a relief valve is missing
Complaints often only surface after six months. That is why we calculate the installation in advance.

- Does chlorine or humid air affect the blower?
"
- In 9 out of 10 cases it does not: the blower stands in a dry plant room and only blows air through the pipework
- With a correct installation including a check valve, chlorinated water does not flow back into the pipe
- Besides bubble benches and jacuzzis, blowers and roots blowers are also used for sand filter aeration in pool installations
