Boll Filter Differential Pressure Indicator Type 4.36.2
For Sale: Boll Filter Differential Pressure Indicator Type 4.36.2


The BOLL Differential Pressure Indica- tor is a robust and compact device indicating the contamination level of the filter elements.

The differential pressure between fil- ter inlet and filter outlet is the meas- urable indicator for the contamination degree of the filter element. When the preset maximum value of differential pressure is reached, the filter needs to be cleaned.

The color of the disc segments visible in the two displays indicates the con- tamination degree: The red segment rises proportionally to the level of contamination. When the segment is completely red, the differential pres- sure limit is reached.


Inside the device is a plunger which is held in zero position by a spring. As differential pressure rises with in- creasing contamination, the plunger is displaced against the resistance of the spring. By magnetic transmission the display disc turns according to the movement of the plunger and shows more and more red segments. The setting of the requested differential pressure is effected by factory instal- lation of a corresponding spring.

Differential Pressure Indicators with integral electronic contacts are pro- vided with two switches which can be independently used either as switch- ing contact or alarm contact. At 75% and at 100% of the preset differential

pressure threshold value, the con- tacts of the two reed-switches are activated magnetically.

The housing of the Differential Pres- sure Indicator is made of coated die-

cast aluminium and for use at an op- erating pressure of up to 100 bar. In case of type 4.46 the internal parts are made of stainless steel and for use at an operating pressure of up to 160 bar.
