Over the last few years, our R&D department has been concentrating its efforts on optimising the efficiency of our machines and offer a new generation of centrifugal Blowers.
As a result, Continental Industrie can now offer a new generation of high efficiency Blowers delivering from 100 to 55.000 m3/h dry, clean, non pulsating air with pressures of 1,1 Bar and vacuums of up to 6.700 mm H2O (WG).
The extremely simple design of our machines guarantees maximum reliability, which is absolutely necessary in all fields of industry in which production depends on the distribution of clean and dry air at a constant pressure.
Cast aluminium parts, precision machining to fine tolerances and the absence of mechanical and wearing parts in contact enable our machines to operate smoothly, practically free of vibration, and with a very low sound level meeting European and American standards.
All our equipment is submitted to a standard 8 hours rotational mechanical test in order to detect any housing heating, vibration or anomaly before shipment.
Casing:
Depending on the model, the inlet and outlet heads and intermediate sections are made of either cast iron or aluminium. In order to suit the pressure requirements, it is possible to vary the number of stages with a maximum of 10 on the small machines and 7 on the larger ones. The heads and intermediate sections are spotted to each other and clamped together by steel tie-rods. The inlet and outlet connections are normally mounted vertically, but if required may be oriented differently. Sealing between the components is ensured by the use of a compound sealant or, in certain cases, by "O" rings.
Impeller Assembly:
The impellers are cast in treated aluminium alloy, and for certain applications are fabricated by riveting. All impellers are statically balanced, then keyed to a ground carbon steel shaft. The complete rotor assembly is then dynamically balanced so as to ensure a minimum vibration amplitude of 30 MIC when running. Different types of impeller are available, ie radial or curved, which enables us to meet a wider variety of duties.
Bearing Housings:
The bearings are mounted in independent cast iron housings. These housings are securely bolted to the inlet and outlet heads, and allow easy access for routine maintenance. The bearings are the only running contacts between the shaft and casing. Sealing of the housing is by graphitized straps, or on the larger machines by segmented carbon rings, which are held together by a stainless steel spring. Leakage is thus reduced to a minimum with this type of seal. In the case of aggressive gases, sealing is by the use of double mechanical seals. The bearings are lubricated either using grease for machines up to 5000 m3/h or by oil replenishment by a constant level oiler for the larger machines.
