Checking the vacuum in your suction boxes on a regular basis can be done in no time.
Measure where it matters – at the Uhle box
The vacuum that is available at the Uhle box for felt dewatering can differ tremendously from the pump vacuum. Just think of contaminations, blocked valves, other vacuum consumers, etc.
Therefore, if you want to know the vacuum at the felt suction boxes there is only one place to measure…
Quickly determine vacuum anywhere
The compact hollow pipe (Ø 8 mm) with smooth tip is narrow enough to get access to practically all types of Uhle box slots.
Checking your complete vacuum system on a regular basis can be done in no time. This enables full control over the vacuum system.
Three good reasons to measure the real vacuum at the Uhle boxes
- pump vacuum ≠ vacuum at the Uhle boxes
- always use the same manometer
- it is easy, quick and reliable
Quickly determine the openess of a press felt
With the Feltest AirSpeed,the air velocity through the press felt can be measured easily. The combination of this measurement along with the measured true vacuum can provide an adequate impression of the felt’s permeability.
Checking and setting the Uhle box vacuum
With the RealVac it is easy to compare the vacuum between the first and second Uhle box. In some cases, there is even a difference between tender and drive side!
The manometer is often placed at the tender side of the machine, but the valves are at the drive side. Simply use the RealVac to set and check the vacuum.
