What is the Delfin MTL 202 LP?

The Delfin MTL 202 LP is a compact, high-capacity industrial dust collector that combines three key technologies: a bypass motor for high airflow, an integrated cyclone pre-separator for initial particle stratification, and the innovative Longopac endless bag system for dust-free disposal. With 360 m³/h airflow and a suction capacity of 2,500 mmH₂O, it is suitable for heavy dust and particle capture in industrial production environments.

Dustop filter cleaning works automatically during operation: when filter pressure rises, the system automatically sends an air pulse through the filter to dislodge accumulated dust. The Longopac system empties without opening the tank — a 20-meter bag cuts off automatically, and the next rolls into place. This virtually eliminates dust during emptying and significantly improves the work environment.

Endless operational safety: With the bypass motor and Dustop cleaning, the MTL 202 LP can run continuously with no planned downtime for filter changes. The automatic systems also mean lower operational complexity and fewer errors from manual intervention.

Questions and answers

What is the Longopac endless bag system?

The Longopac endless bag system is an intelligent solution for safe, dust-free emptying of the dust collector's collection tank. Instead of replacing a full bag every time, the next bag in a continuous 20-meter roll can be pulled down. When one bag fills up, it cuts off automatically and the next bag rolls into place. The system seals each bag individually, preventing dust escape during emptying.

How does Dustop filter cleaning work?

Dustop is an automatic filter cleaning system that operates continuously during operation without stopping the vacuum pump. When filter pressure rises above a set threshold, a pneumatic valve opens and sends a brief air pulse through the filter to create an inward blast that dislodges accumulated dust from the filter surface. The system repeats automatically as long as the vacuum lid is closed and the unit is running. This means fewer filter blockages, longer filter life, and reduced pressure loss.

What role does the cyclone play?

The integrated cyclone pre-separates large particles from the incoming airstream before the air reaches the filter. Gravity forces heavy particles to fall into the cyclone's collection cone, while finer particles pass on to the cartridge filter. This reduces filter load, extends filter life, and improves overall filtration efficiency. The cyclone operates automatically with no moving parts or maintenance.

Can the filter be upgraded to HEPA?

Yes. As an option, the MTL 202 LP can be equipped with an H14 absolute filter (HEPA, 99.995 % MPPS). This secondary filter is positioned after the cartridge filter and captures even the finest particles. The H14 version is particularly suitable for pharmaceutical production, chemicals, or very fine dusts where particle control is critical.

Is the MTL 202 LP suitable for pharmaceutical production?

In standard configuration, the MTL 202 LP is well-suited for high-volume dry dust collection. For pharmaceutical environments with OEB or GMP requirements, upgrade with H14 absolute filter (HEPA) and grounding against electrostatic buildup is recommended. The Longopac system also ensures minimal dust exposure during emptying. Contact us for consultation on the right configuration.

What options are available?

The MTL 202 LP is offered with the following options: H14 HEPA absolute filter, class M antistatic filter, grounding (ESD), grounding plus antistatic filter plus chain, accessory basket, 3 m hose holder, differential pressure alarm system. All options are customized at the time of order to meet specific production and safety requirements.
