- Dehydrating breathers
Standard
HAMPs dehydrating breathers are primarily used for oil-insulated transformers where they prevent moisture in air from coming in contact with the transformer oil and thus lowering insulation properties.

ART.NO | TYPE | Max oil weight (kg) | Comp. Weight (kg) | Silica gel weight (kg) | Total height (mm) |
|---|---|---|---|---|---|
3040 1010 | 4101-A | 1000 | 0,6 | 0,25 | 140 |
3040 1020 | 4101-B | 2000 | 0,7 | 0,50 | 205 |
3040 1030 | 4101-C | 4000 | 0,9 | 1,00 | 325 |
Step by step
1. Screw the dehydrating breather onto the pipe underneath the expansion tank.
2. Loosen the wing nuts a few turns in order to enable the plexiglass container of the dehumidifying agent to be removed sideways.
3. Remove the oil trap and fill the glass bowl with transformer oil up to the level mark. A The oil for this can be tapped off from the test valve on the expansion tank.
4. Check that both gaskets are correctly located, and fit the container. Tighten the wing nuts firmly, to ensure good sealing.
ART.NO | TYPE | Max oil weight (kg) | Comp. Weight (kg) | Silica gel weight (kg) | Total height (mm) |
|---|---|---|---|---|---|
3040 1040 | 4170 | 800 | 0,35 | 0,18 | 138 |
Step by step
1. The dehydrating breather is designed for top mounting. Screw it onto the expansion tank filling hole.
2. Loosen the wing nuts a few turns so that the plexiglass container with its cover can be removed sideways.
3. Fill the plexiglass container with silica gel up to the oil trap support.
4. Remove the oil trap, and fill the glass bowl with transformer oil up to the level mark. The oil can then be tapped off from the test valve on the expansion tank.
5. Check that both gaskets are correctly located, and fit the container. Tighten the wing nuts firmly, to ensure good sealing.
ART.NO | TYPE | Max oil weight (kg) | Comp. Weight (kg) | Silica gel weight (kg) | Total height (mm) | 3040 1050 | 4130-2 | 8000 | 2,7 | 2,00 | 319 |
|---|---|---|---|---|---|
3040 1060 | 4130-4 | 16000 | 3,5 | 4,00 | 515 |
3040 1070 | 4140 | 32000 | 5,7 | 8,00 | 916 |
Step by step
1. Screw the dehydrating breather onto the pipe under- neath the expansion tank. The cover has a location flange. With types 4130-4 and 4140 the base also has a location flange.
2. Loosen the three upper wing nuts a few turns and then lower the front retainer bolt. Remove the plexiglass container and fill it with silica gel.
3. Check that both gaskets are correctly located, and fit the container. Tighten the wing nuts firmly, to ensure good sealing.
4. Remove the oil trap bowl by loosening the wing nut on the underneath and turning the retainer forwards 90 degrees. Fill with transformer oil up to the level mark on the oil trap.
5. Make sure the oil does not moisten the silica gel as this will destroy the gel.
