Flovac’s vacuum sewerage system is more effective than the traditional gravity system in installations. This is due to the fact that the net of small vacuum pipes can be installed in the ceiling (or fake ceiling), without caring about the drainage system.
Furthermore, the vacuum pipes system is not conditioned to a gradient thanks to the lifts. In comparison, the gravity draining systems need larger gradients and diameters. The vacuum valve controller works without electric connection.
The vacuum central installation is designed according to the needs of each installation, with a minimum set of equipment:
The vacuum pipes system is formed by all the main and secondary lines, verticals and horizontals from the vacuum central installation to the vacuum valve.
The main material used for this net is the PVC-U pipe in PN10. This material has a smooth and not porous interior, has a good resistance to the agents from the waste water and it’s capable to stand negative pressures up to -1000HPa (-1bar). The accessories are made with PVC-U as well and their unions are glued. It’s possible to use other materials to non habitual conditions.
The setting of the vacuum net provides to each device a connection formed by a sectional valve, a vacuum outlet and an interconnection valve. When the pipes network is being built, it can be used:
The vacuum interface devices divide the atmospheric pressure phase from the pipe’s depression phase and they allow eliminating the water in the storage tank. The three components in the aspiration points are:
For all these reasons, the Flovac’s vacuum sewerage system is the most effective solution for establishments, especially supermarkets.
