SFC.

Breather cap with sealing closure

Air filter :
Polyurethane foam mesh “tech-foam” (polyester base), air filtration 10 µ.
Assembly instructions :
1) Screw the threaded connector by means of a hexagon key, maximum tightening torque 8 Nm (Fig. 1).

2) Insert the “tech-foam” filter in its proper upper housing.

3) Fit the cover on the threaded connector by properly matching the two different teeth (different for shape) of the cover and the relevant knurling on the upper part of the threaded connector (Fig. 2). On this knurling there are two stop positions, where the teeth of the cover are fitted: one is for the breather closure and the other one is for the sealing closure.

4) Breather closure. After fitting the cover (see point 3), turn it following the CLOSE arrow (clockwise) until the first click. In this position the cover is locked by means of the teeth fitted in the relative stop housing of the knurling: this is a guarantee against accidentaly unscrewing. In this position the index on the cover marked with 1 is in line with the index on the flange of the threaded connector (Fig. 3).

5) Sealing closure. To reach sealing closure from breather closure (see point 4), turn the cover following the CLOSE arrow (clockwise) until the click. In this position the cover is locked by means of the teeth fitted in the relative stop housing of the knurling: this is a guarantee against accidentaly unscrewing. In this position the index on the cover marked with 0 is in line with the index on the flange of the threaded connector (Fig. 4).

6) To reach breather closure (index on the cover marked with 1 in line with the index on the threaded connector) to sealing closure (index on the cover marked with 0 in line with the index on the threaded connector) just turn the cover following the OPEN arrow (anticlockwise) until the click (Fig. 3).

7) By turning the cover following the OPEN arrow (anticlockwise), from breather closure it is possible to remove the cover from the threaded connector after the click, thus allowing the operator to clean the components or to substitute the “tech-foam” filter (Fig. 5).

SFW.

Double-valve pressurised breather caps

Features :
The use of SFW. pressurised breather caps 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.
Flat dipstick :
Flat section phosphatised steel.
On request and for sufficient quantities dipstick can be supplied in different lengths and/or complete with MAX-MIN level lines.

SFW-VP

Double-valve pressurised breather caps vandal-proof

2. Unscrewing
Turn the cap clokwise until one of the two resistance points is reached. Only at one of these two positions the key, which couples the cover to the threaded connector,  can be completely  inserted and the cap can be unscrewed.
1. Screwing
Take out the key and screw the cap clockwise until the friction-click controlled torque mechanism is engaged so that to guarantee the best sealing of the packing ring. The maximum torque is reached at the first mechanism release (click). After that, the cap can neither be screwed (to protect the packing ring) nor unscrewed (to protect the cap from any tampering attempt).
WARNING: during screwing the key must not be inserted.

GN 743.2

Oil level indicators

Features and applications :
Oil level indicators GN 743.2 offer the following features:
genuine glass of high stability and scratch proof. The sealing is achieved with an O-ring on the periphery and not on the face edge of the glass. Leak tightness is therefore not affected by axial pressures.
The outside diameter of these oil level sight glasses with recessed hexagon is chosen to match mounting holes for tube fittings according to DIN 3852.
The seal is housed in a groove and it can therefore not be lost. In addition, this groove prevents the seal from being extruded when the sight glass is tightened. The location of this seal allows also the use of a softer Elastomer which guarantees better and easier sealing.
Oil level indicators GN 743.2 can be used on pressurised oil tanks. Tests regarding maximum pressure are available on request.
Also, these oil level sight glasses are suitable for applications with subpressure.
Material :
Brass.
– Execution A: with technopolymer (Polysulfon) contrast screen.

GN 743.7

Oil level indicators with conical threading

Features and applications :
The conical thread of the oil level indicators GN 743.7 makes a metallic seal possible. When tightening the conical male thread R it blocks itself with the appropriate cylindrical female thread Rp.
At the reference level the R-male thread has the same thread diameter as the Rp-female thread, so that it can be screwed in by hand. The strong tightening by means of a tool increases the length of engagement and seals the screw connection. Additionally a sealant (hemp or teflon band) is usually used. The R-thread is “roughened”, so that the sealant does not shift when screwing in.
Oil level indicators GN 743.7 can be used on pressurised tanks. Data of pressure and vacuum pressure tests is available.
Material :
Brass.
– Version A: with technopolymer (Polysulfon) contrast screen.
– Version B: without contrast screen.

Column level indicators

Assembly :
– By means of the supplied set screws and nuts.
– By means of the supplied set screws, without nuts, by tapping the two holes in the reservoir walls, if they are thick enough.
To ensure the best sealing of the O-rings it is recommended to apply the maximum torque on the nuts as reported in the table and a roughness of the gasket application surface Ra = 3 µm.
Contrast screen :
White lacquered aluminium. The housing, in the appropriate external rear slot, guarantees the best protection from direct contact with fluid, avoiding yellowing effect due to the prolonged action of the fluid at high temperatures.

Assembly instructions :
To ensure proper assembly of the indicator, please follow these instructions:
1. Set the minimum oil level of your reservoir.
2. Drill two holes on the reservoir wall. The lower hole axis should be drilled at “m” distance (see table) under the minimum oil level.
“m” is the minimum oil level allowed. This is the level from which the float starts to be moved upward.
The value “m” is calculated with an oil density of 875 Kg/m³ at 15°C.
If the red line of the contrast screen appears, the oil level is under its minimum level allowed.

FM KIT

Fast Mounting Kit

Assembly of the indicator with the Fast Mounting Kit :
1. Follow the assembly data reported in the table.
2. Make sure that the hole in the plate does not have any burs, especially inside the reservoir.
3. Before assembly the indicator on the reservoir, slightly tighten the nut by hand against the packing ring. We advise you, then, to deform slightly the threaded end of the screw in order to prevent the nut from falling into the reservoir while disassembling the indicator.
4. To disassemble the indicator from the reservoir, just rotate the screw 3/4 of a turn keeping the plastic part of the indicator under tension (pulling).
Features :
The Fast Mounting Kit has been designed for mounting level indicators series HCX. (measures 76,127 and 254) from the outside when nuts cannot be fitted from the inside of the reservoir.

GN 7403

Breather strainers

Accessory :
Mounting nut GN 543.1
Information :
Breather strainers GN 7403 are used in enclosure and device construction. Inserted into the wall of the enclosure, they ensure pressure equilibrium between the inside of the enclosure and the outside.

Any dirt and dust particles carried by the medium (usually gas) are prevented from exiting depending on the mesh size. This protects the insides of sensitive devices and machinery parts from dirt and pollution and also protects the environment from any exiting dust.

The outside diameter of the enclosure with the recessed hexagon matches the bolt mounting holes for DIN 3852 threaded pipe connectors.

The sealing ring is embedded in a radial and plane-sided recess which makes the seal captive and prevents it from being squeezed out during tightening.

Assembly instruction:
For mounting on walls of less than 4 mm thickness, please use mounting nut GN 543.1.
