The Microlube Plastic Top Filter Bag

Our bags are manufactured with the best, most consistent polyester and polypropylene needle felt in the industry. Silicone free and FDA approved, our media comes standard with fibre free surface treatment to prevent fibre contamination downstream.

Our Filter Bags are “rounded bottom welded configuration” to better fit your filter bag basket. The retainer seal of the plastic top Filter Bag is moulded from only virgin resins and offers a unique four point positive seal.

This unique design adapts to almost any filter housing, ensuring bypass free filtration. Raised integral handles make bag removal quick and easy, saving you time and money.

The Microlube Steel Ring Filter Bag

The unique thermal plastic bonding process has been developed to produce welded filter bags with steel ring retainers. The result is the best ring seal in the industry for one very important reason… the lump.

Our steel ring filter bags have no lump, another industry first. Our steel ring felt filter bags have no needle holes in the seam, so you get better filtration efficiencies. All welded filter bags are available in polyester and polypropylene felt in micron ratings from 1 – 200.

The Microlube Extended Life Filter Bag

As the name implies, extended life filter bags are designed to give longer service life, therefore reducing operating costs and process down time. The unique blend of fibres in extended life media offers 2 – 5 times the dirt holding capacity of traditional needle felt material.

When you compare a cross section of traditional needle felt with that of extended life media, the improved dirt holding capacity is obvious.

Thermal bonded seam construction provides improved filtration efficiency by eliminating needle holes and thread.

The Microlube High Efficiency Filter Bag

These filter bags have been developed for demanding applications that require critical particle size retention and dirt holding capacity. They are constructed from chemically resistant polypropylene micro fibre which can be used in a wide range of process applications.

This unique product line is available in all industry standard sizes with efficiencies up to 99.9% and down to 0.5 micron.

The Microlube Nylon Monofilament Filter Bag

Nylon monofilament (NMO) precision woven filtration media offers enhanced removal characteristics and improved strength and durability. Each filament in the weave has been extruded with a consistent yarn diameter and the smooth extruded surface allows the structure to be cleaned and reused in certain applications. NMO filter bags are available in micron ratings from 50 to 1,250.
