Metal working fluids, also known as lubricants, are used in a lot of tools that are used in the metal forming industry. Tools that roll, cut, form bend or stamp metal all use these fluids in order to operate. However, the warehouses where the machinery is used can be dirty, dusty and have metal shavings in the air. All of these particles can wind up inside of the machine and make their way to the fluid. Fluid filtration bags act as filters. As the fluid flows through the bag, they filter out all of the dirt, dust and metal shavings to prevent them from making their deeper into the machine and causing damage. But unlike a filter, a bag can hold more debris, reducing the frequency in which they need to be changed. If you are looking to purchase metal working bags, it is important to understand that they are not all the same. Here are a few of the key differences between the metal working fluid filtration bags and what you need to know as you buy these filter bags.
The Micron Level
As you look at the filter bags, pay close attention to the micron level. The micron level, also known as the filtration level, determines the size of the holes in the bag. The greater the number, the more filtration protection the filter offers. This is because the holes are smaller and tighter. However, this can also affect the flow of the fluid through the bag. As such, carefully consider the micron level to ensure fluid flows like it should while still removing impurities.
The Flow Rate
Speaking of the flow of the fluid, another important factor to consider is the flow rate of the filter bag. The flow rate is measured in liters per minute. If the flow rate is 1, that means one liter of fluid can pass through the filter bag per minute. If the rate is 100, that means 100 liters can pass through per minute. You need to find out how much fluid flows through your machine per minute to ensure the filter bag can handle the flow needed for your machine to properly operate.
Single-Stage Versus Multi-Stage
Lastly, consider whether the metal working fluid filtration bag is a single stage bag or a multi-stage bag. A single stage bag has one filtered area where the fluid flows and the debris is kept. A multi-stage bag requires the fluid to flow through different barriers in the bag that catch and filter debris. A multi-stage bag may catch any debris that may have been missed the first time around, but it also slows the flow of liquid. As such, you have to consider this carefully.
Knowing what to look for as you look to buy filter bags for your metal working tools will help you select the right bags for your machine's needs.
