Downflo Oval Cartridge (DFO)

Lượt xem : 102

The Donaldson Torit® Downflo® Oval cartridge dust and fume collector sets the standard for industrial dust collection – by providing a 25% increase in airflow capacity, improved airflow path, and a 29% increase in pulse cleaning pressure. These compact, high-efficiency units use high efficiency oval-shaped cartridge filters, especially well-suited for filtering the sub-micron dust

A Family of Over-Achievers

The high performance Downflo Oval (DFO) family of dust collectors provides up to 25% more filtration capacity than other same-sized cartridge collectors. Powered by proprietary Ultra-Web® fine fiber filtration technology, DFO delivers cleaner air, up to two times longer filter life, and greater cost savings.

A smaller collector helps lower the initial purchase price, reduces filter replacement costs and opens up valuable manufacturing floor space.

DFO Offers:

Lower initial cost per cubic meter of air per hour (m3/h) / cubic foot of air per minute (cfm)
Higher efficiency—cleaner air
Lower pressure drop—greater energy savings
Fewer filter changeouts
Reduced filter disposal cost
Easy system setup

Less maintenance

Outperforms Other Collectors

DFO collectors offer some strong benefits that distinguish them from all other collectors available in the market today.

Easy to Use
Quick-release handles provide easy cover removal and faster filter access.
Compact
Smaller footprints for applications that require maximum cleaning efficiency in even smaller spaces.
Powerful
DFO collectors provide 25% more capacity than same-sized dust collectors.
Cost Effective
The proprietary ExtraLife Filter Cleaning System averages up to 30% increase in pulse cleaning energy for unmatched cleaning ability.
Innovative
Unique oval-shaped Ultra-Web cartridge filters provide the longest filter life and highest filtration efficiency—which lowers cost.

Unique Oval Shape Contributes to Higher Airflow Capacity

The Downflo Oval filter design is a reflection of Donaldson Torit’s commitment to technical research and development. High performance oval-shaped filters handle up to 25% more airflow without increasing velocities, which can cause filter abrasion. Sophisticated FLUENT® Airflow Modeling Software revealed that oval-shaped cartridge filters have fewer areas of high velocity, resulting in a lower potential for media abrasion and increased filter life.
