Silencers

SILENCERS
These mufflers deaden both mechanical sounds and air noise for a safer, more productive plant environment. These silencers have a real impact on reducing the sound emanating from choppers, and other machine functions. They are a good first step in any effort to meet sound reduction requirements.

  • • Fan Inlet or Machine Inlet

In-line Static Neutralizers

IN-LINE STATIC NEUTRALIZERS
Important when moving woven and non-woven materials through a system, as well as lengthy poly-coated materials. These neutralizers ionize the air inside ducts to remove static charges caused by conveyed materials rubbing against duct work. This prevents material from sticking to separator walls, improving conveying efficiency. Used on 480 volt systems.

Balers

BALERS
Used when scrap needs to be collected in bales. They are particularly useful in systems requiring continuous material collection.

  • • Automatic or Manual tie machines are available.
  • • Units to collect 200 lb. to 500 lb. bales.

Diverter Valves

DIVERTER VALVES
Route conveyed materials where they need to go. Diverter Valves operate like railroad switches and are usually placed in-line with duct work, but can also be placed at the bottom of cyclone separators. Standard sizes are used in ductwork from 4” to 30” in diameter with custom sizes available when needed.

Eductors

EDUCTORS
Many applications require special considerations to ensure material doesn’t come into contact with the fan. Eductors take trim or scrap directly to the receiver circumventing fan contact.

Sound Enclosures

SOUND ENCLOSURES
Used where there are more stringent sound restrictions or when material-carrying ducts come in and out of machines creating sound hazards. These enclosures surround machines, inlets and outlets. They are often used in conjunction with Silencers.

  • • Can be acoustically lined or fully insulated for extreme cases.

Material Air Separators

MATERIAL AIR SEPARATORS
There are a variety of ways to separate materials from air, depending on the type of materials and existence of dust in the system. All are designed to exit air out of the system while heavier materials drop down.Perforated Elbow: For materials that do not produce static charges and contain no dust. Air exits through a screened vent at the elbow allowing materials to drop into the receiving bin.Perforated Elbow with Shroud: Includes filters to capture dust in the system.MAS Unit: Material Air Separator is used when there is high dust content that may be an explosion hazard. Dust is pulled off materials and deposited in Dust Collector.Cyclone Separators: These round separators create swirls of air allowing air to exit the system out the top while materials drop. Used on 20” to 24” dia. conveying systems.

Dry Dust Collection

DRY DUST COLLECTION
As dust-laden air moves through these large filter units, it sticks to filter bags. Compressed air is used to blow air into the collector. Multiple filter media and pleating configurations are used to meet different system requirements.

Spark Detection

SPARK DETECTION
When handling potentially explosive materials and dust-laden systems, these products detect ignition sources in the air stream and activate sprinkler heads installed in the ductwork to prevent ignition.

Fans

FANS
There are a variety of fans used in material handling systems depending on system configuration and air movement requirements. The key considerations are the size of the system ductwork, the material being conveyed and the physical arrangement between fan and system.

  • • Air Handling Fans provide air to certain areas of a system to provide airflow.
  • • Material Handling Fans are used when material-laden air must be moved. These fans may transfer, chop and trim different materials.
  • • Various sizes and fan arrangements are used to match system requirements.

Specialty Intake Hoods

SPECIALTY INTAKE HOODS
Custom designed hoods improve the efficiency of trim or product collection into ductwork. Flared inlets are combined with air lubricated chutes and mounting brackets.

  • • Match existing machine inlets, or design new.

In-line Trim Choppers

IN-LINE TRIM CHOPPERS
These 2 or 4 blade rotors chop metal, paper or plastic ribbons into conveyable pieces. Different blade types are used depending on the material being chopped.

Wet Dust Collection

WET DUST COLLECTION
Trimvac® units provide a quicker way to separate dust from conveyed materials. Air is sucked out the top of the unit while materials are saturated with water. In this manner the air exhausted from the system is as clean as possible. Most often this means air does not even have to be scrubbed.When scrubbers are still required, Compass uses Rotoclone® systems. These systems are usually placed right after MAS Separators on systems with air movement up to 20,000 CFM.

Electrical Controls

ELECTRICAL CONTROLS
The nerve center of every system. Compass uses a wide variety of controls to match system needs. Major considerations include labor, material and safety. Depending on these considerations, we use any or all of the following types of control and accessories.

  • • VFD Drives
  • • Motor Starters
  • • Compact Blocks
  • • PLC’s and HMI Displays
  • • Push Buttons
  • • Stack Lights and Sirens
  • • Air Conditioners
  • • Voltage Rectifiers
