Candle Filter Selection Guide

Selecting the right Candle Filter requires careful consideration of several key factors and performance parameters to ensure that the equipment meets specific process demands and efficiency requirements:

Filtration Accuracy
Filtration accuracy determines the minimum particle size that the filter can remove. Candle filters offer a wide range of precision levels, which can be selected based on the actual application.

Capacity
Capacity generally refers to the volume of liquid a filter can process per hour (flow rate). The chosen filter should have a capacity equal to or greater than the process requirement.

Operating Pressure
The operating pressure of the candle filter should be equal to or higher than the system pressure to avoid damage under normal working conditions.

Operating Temperature
The filter’s temperature range must align with the system’s operating temperature. Extreme temperatures, whether high or low, can affect filter performance and lifespan.

Filter Media
Filter media should be selected according to the properties of the liquid (such as acidity, alkalinity, corrosiveness, or viscosity). Candle filters are available with filter elements made from stainless steel, ceramics, polypropylene, and other materials.

Number and Arrangement of Filter Elements
The quantity and arrangement of filter elements affect the filtration area and efficiency. More filter elements typically provide larger surface area and higher processing capacity.

Backwash and Cleaning System
Most candle filters are equipped with a backwash system to remove blockages from the filter elements. Consider the efficiency, reliability, and ease of maintenance of the cleaning system.

Automation Level
Highly automated candle filters reduce manual operation and enhance productivity. Optional features include automatic tightening, automatic residue discharge, and remote monitoring.

Equipment Size and Weight
Choose equipment dimensions and weight according to installation space constraints to ensure ease of installation and maintenance.
