What is Delfin DM3 EL LP?

The Delfin DM3 EL LP is a powerful industrial vacuum designed for large work areas, construction sites, workshops, and production facilities. The 3.45 kW single-phase bypass motor delivers 540 m³/h airflow and achieves 2,500 mmH₂O suction. The machine is equipped with the Longopac endless bag system — a patented system that makes emptying dust-free and safe. The primary filter is a Polyester ANT M star filter with 30,000 cm² filtration surface and manual cleaning.

The adjustable height via retractable column enables the DM3 EL LP to be placed in a van for transport between locations — ideal when work areas change. When parked, the column folds down, reducing vehicle space during transit. The construction is fully painted steel, robust and suited for industrial and building environments.

Longopac system — high containment safety: Instead of handling single-use bags, dust is rolled up in an endless bag inside the machine. As the bag fills, it is forced out through a sealed emptying point at the top and automatically cut off. This means minimal exposure to fine dust, no air release during bag changes, and safe handling of chemicals and sensitive materials.

Questions and answers

Longopac is a patented system where dust is rolled up in an endless bag inside the machine. As the bag fills, it is forced out through a sealed opening at the top and automatically cut off. This means: no dust exposure during bag changes, no air release when replacing bags, and safe handling of fine dust and powders. A 20-meter Longopac roll typically provides 5-10 bag cycles, dramatically reducing operator workload compared to traditional single-use bags.
The adjustable height feature (via retractable column) allows the DM3 EL LP to be placed in a van or truck for transport between job sites. When not in use, the column folds down, reducing the footprint during transport. This makes it economical to run a single DM3 EL LP across multiple locations instead of purchasing several fixed units, and it saves time when handling at job sites, workshops, or facilities.
ANT M stands for 'Antistatic, Polyester, Class M' according to European filter classifications. The polyester material provides high filtration and durability. The antistatic property means the filter is coated or designed to reduce electrostatic charge, preventing dust clumping during operation. Class M rating means the filter and system are approved for collecting low-explosive materials—typically Class M substances such as wheat, sugar, and iron oxide dust.
Yes. The DM3 EL LP can be equipped with an H14 HEPA absolute filter with 26,500 cm² filtration surface as an option. This filter is typically mounted after the primary Polyester ANT M star filter, creating a two-stage filtration setup. With the H14 filter, the machine achieves 99.995% particle retention at MPPS, making it suitable for pharmaceutical production, medicine manufacturing, laboratories, and other critical applications. Contact us for advice on the correct H14 installation.
The DM3 EL LP requires significantly less maintenance than many competitors. The primary maintenance item is Longopac bag roll replacement (after the 20-meter roll is used) and occasional manual filter cleaning if dust loading is high. There are no motor brushes or carbon elements to replace, and the bypass motor requires no periodic lubrication. An annual system check (seals, plugs, guides) is recommended to keep the machine in top condition.
Yes, absolutely. This is one of the DM3 EL LP's primary strengths. The combination of the antistatic Polyester ANT M star filter (30,000 cm² surface) and especially the Longopac system makes it ideal for fine dust, powders, and chemicals. The Longopac system drastically reduces exposure when the bag is changed, and it ensures all dust remains sealed during emptying. For very fine particles or handling in pharmaceutical environments, the H14 HEPA filter is recommended as an upgrade.
