Frequently Asked Questions

General Information
What is a Longopac® dust bag?
Longopac® is a continuous, endless bag system used with compatible Husqvarna dust extractors. Instead of traditional single disposable bags, Longopac uses a continuous plastic tube that you pull down as it fills. When full, you tie it off, cut it, and continue with fresh material — keeping dust fully contained and minimizing exposure.
What are the measurements in the variant options (4x23M, 4x20M, 1x25M)?
The format represents the number of rolls multiplied by the length of each roll in meters. For example, 4x23M means you receive four rolls, each 23 meters (approximately 75 feet) long. Because Longopac is an endless sleeve system, you are buying total bag length — not individual pre-sized bags.
How many individual bags can I expect from one roll?
It depends on how much length you pull per change, but most contractors pull about 3 feet per bag section. A 23 meter (75 foot) roll typically produces approximately 25–30 tied-off bag sections. Heavier dust loads may require shorter sections per change.
Choosing the Right Variant
What is the difference between 53 micron and 66 micron Longopac bags?
Microns refer to the thickness of the plastic material. 53 micron (Super-Strong) is ideal for general concrete grinding and dust extraction. 66 micron (Mega-Strong) is thicker and more puncture-resistant, recommended for heavier debris, sharp particles, or high-volume industrial grinding applications.
Should I choose a 4-pack or a single roll?
Contractors running grinders or saws daily typically choose 4-pack options to reduce downtime and lower cost per roll. A single 1x25M roll is often ideal for lighter use, smaller crews, or occasional dust collection needs.
How do I decide between 20M, 23M, or 25M roll lengths?
Longer rolls simply provide more total bag length per cassette. A 23 meter roll (approximately 75 feet) is common for mid-to-heavy daily use. A 25 meter roll offers slightly more total yield. Choose based on how frequently your crew fills bag sections during grinding or cutting operations.
Usage & Replacement
How often do I need to change the Longopac bag?
You change the bag section when it becomes full — not on a time schedule. Most crews pull down about 3 feet of material, allow it to fill, then tie and cut it off. Heavy grinding jobs may require multiple bag sections per shift, while lighter cleanup work may only use a few sections per day.
What happens if I overfill a bag section?
Overfilling can restrict airflow and reduce extractor performance. For best suction and dust containment, tie off sections before they become overly heavy or compacted. Regular section changes help maintain optimal airflow and filtration performance.
Is Longopac safer than traditional dust bags?
Yes. Because the system remains closed during changes, Longopac significantly reduces airborne dust exposure compared to removing and replacing traditional disposable bags. This is especially important when collecting fine silica dust.
Compatibility & Installation
Which machines use Longopac® bags?
Longopac bags are designed for compatible Husqvarna dust extractors and select professional dust collection systems that use the Longopac cassette system. Always confirm compatibility with your specific dust extractor model before purchasing.
How do I install or replace a Longopac roll?
Installation involves loading the roll cassette into the extractor housing, securing the starting end of the sleeve, and pulling down the initial section before use. When a section fills, tie it off using zip ties or integrated ties, cut below the tie, and continue pulling fresh material.
Warranty & Support
Is this an OEM Husqvarna product?
Yes. These Longopac® dust bags are genuine Husqvarna OEM accessories designed for proper fit and performance with compatible extractors.
