Ventilating Filters up to 225 gpm, L1.0406/L1.0506/L1.0706/L1.0807
Application area
Ventilation of tanks for hydraulic and lubrication systems, and gearboxes.
General
The oil levels in the tanks of hydraulic systems are subject to continuous
variation due to temperature changes and the operation of cylinders and
pressure vessels.
In order to prevent over pressure in the tanks, an exchange of air with
the external atmosphere is necessary. By the use of a ventilating filter, the
outside air that is drawn in is filtered and the ingress of dust is therefore
prevented.
Special features
The ventilation openings are designed so that dust on the surface of the
tank is not drawn in, and that the ingress of spray and rainwater is largely
prevented.
The use in marine applications presents no problem due to the use of
synthetic materials and stainless steel.
Design
Flow direction bi-directional (air IN/OUT). The star-shaped pleating of the filter material results in:
- large filter surfaces
- low pressure drop
- high dirt-holding capacities
- long service life |
|
Air breather filters allow for the flow of clean air to and from a closed chamber where balanced atmospheric pressure is required, such as in gear boxes, bearings operating at high speed and hydraulic power packs.
Filton air breather filters ensure that there is no dangerous build up of pressure or vacuum due to temperature or volume changes. The high quality sintered element prevents the ingress of air borne foreign particles. |
|
MAHLE crankcase ventilation systems reliably clean the gases contaminated with oil mist from the crankcase. The oil consumption can therefore be reduced further and the emission limits fulfilled. The oil mist separator integrated in the crankcase ventilation serves to separate the gas and fluid components. The separated oil is then returned to the oil circuit and the cleaned air supplied to the intake system.

Compoflex™ 150 for Resin Infusion
In the resin Infusion process, the dry fibre material is placed directly in the mould. A distribution fabric or grid is installed to ensure corect resin flow and optimal vacuum distribution. Between the dry fibre material and the distribution fabric, a peel-ply is installed as a seperator. Compoflex 150 replaces the peelply and ensures easy peeling, leaving a clean surface.
Designed without a bleeder layer, Compoflex 150 is ideal for for the resin infusion process. |

Compoflex™ 400 for Vacuum Bagging
In the vacuum bagging process the lay-up consists of a laminate, peel-ply, release film and a breather/bleeder fabric. Compoflex 400 can replace all of these products, simplifying the process considerably.
Designed with a maximum size bleeder layer, Compoflex 400 is ideal for the vacuum bagging process. |

The use of SFW/WP pressurised breather cap which create a pressure plenum chamber right above the oil level within tested limit conditions, in order to avoid any reservoir deformation, offers the following advantages:
- reduces reservoir air volume intake keeping clean oil and filter
- improves suction pump action during working conditions reducing cavitation phenomenon
- prevents fluid leakage when the system is part of a mobile unit
- reduces foam in fluid. |
