Understanding Dust Extraction Bag Measurements - Square
When dealing with dust extraction bags, it can be challenging to work out the different measurements provided. Here, we will break down the dimensions of these bags and explain how to select the right size for your needs.
Understanding the Measurements
Let's start with a typical dust extraction bag, which might be labelled as a 580mm square bag. The dimensions for such a bag might be listed as 610 x 1168 x 167 mm. These figures can be confusing at first glance, so let's clarify what they represent:
When the bag is laid flat, it measures 610 mm in width. The flat length of the bag is 167 mm. However, when the bag is fully opened, its width expands to 1168 mm.
This expansion is due to the gusseted bottom of the bag, which allows it to accommodate more volume when filled.
Using the Bags
These bags are predominantly designed to fit inside collection bins. Unlike bags that are used in high-pressure environments (like 400, 500, or 600mm diameter bags), these are intended for use in bins that collect particles falling into them, making them easier to empty.
To fit the bag into the bin:
Take the bag, fold it in half, and place it inside the bin.
Ensure there is enough room for the bag to expand and fold over the edges of the bin. This allows for a secure fit and easy removal when full.
Selecting the Right Size
To determine the correct size of the extraction bag for your bin, you need to consider the total circumference of your bin. For example, if you have a bin that measures 600 mm by 400 mm, you would calculate the total circumference as follows:
1) Add the sides, including any lips or flanges: 600 + 400 = 1000 mm
2) Multiply by 2 (since there are two sets of sides): 1000 mm x 2 = 2000 mm
3) Compare this total perimeter with the middle dimension of the bag (1168 mm in this example). Double the middle dimension: 1168 mm x 2 = 2336 mm. Since 2336 mm is greater than the bin's perimeter of 2000 mm, the bag will fit comfortably.
Thickness and Durability
The thickness of these dust extraction bags is typically 400 gauge prime material. Although they are not as robust as those designed for high-pressure use, they are still quite durable. These bags can comfortably hold up to 25 kg and have been tested to withstand weights over 40 kg. They also offer good puncture and tear resistance, making them suitable for heavy-duty use.
In summary, by considering the flat and fully open measurements, as well as the total perimeter of your bin, you can ensure a secure and efficient fit. Additionally, these bags' thickness and durability make them a reliable choice for managing dust and particles in various settings.
