What is a Differential Pressure Indicator?
A differential pressure indicator is an instrument that checks the pressure difference at the inlet and outlet sides of a filter. As filters become clogged with dirt or debris, flow resistance builds up, and pressure drop increases. The operator is signaled when the pressure difference rises above a set limit in this example, which is 0.6 bar, to undertake appropriate filter maintenance or replacement.
Key Features of the Bollfilter 4.36.2
Bollfilter 4.36.2 boasts precision, resilience, and readiness for integration within Boll & Kirch filter systems. Some of its salient features include:
Pre-calibrated at 0.6 bar: Enables immediate warning once filter elements become clogged.
Visual Indication: Simple yet clear visual pointer enables easy inspections without power and sensors.
Durable Build Quality: Constructed to last in harsh marine and industrial conditions, including corrosive environments.
Compliant with Boll Filters: Engineered to exactly match a broad range of Bollfilter models for maximum system reliability.
Maintenance-Free Design: No power supply or complex installation—simply plug and play.
Applications
The Bollfilter 4.36.2 is used extensively across industries where filtration is of the utmost importance. Typical applications include:
Marine engines – to safeguard fuel and lubricating oil systems.
Power stations – maintaining oil filtration systems to avert equipment wear.
Chemical processing equipment – maintaining purity in fluid systems.
Industrial hydraulic systems – maintaining cleanliness of hydraulic fluids to prevent equipment damage.
Why the 0.6 Bar Threshold is Important
The 0.6 bar threshold is a critical point at which filters are considered too clogged to function optimally. By alerting operators at this pressure level, the Bollfilter 4.36.2 helps avoid costly downtime or equipment failure. It essentially acts as a guardian for your filtration system—providing peace of mind that the machinery is running clean and safe.
