Titus has fielded many inquiries about our EcoShield liner. All literature associated with this product can be found on our website. The liner submittals show all of the ASTM & NFPA standards that the liner is in compliance with. EcoShield liners can be ordered as stand-alone rolls (seen in the table below):

The roll sizes above are the standard stock sizes, with custom sizes being available between the maximum roll widths of 60” in lieu of the standard 48” width. We also have EcoShield sample kits, which are packaged in a box that can have up to 8 liner samples. A custom insert highlights competitive advantages. Contact Titus Marketing for demo kits.

Some of the great benefits of EcoShield include:

·        Quiet operation: Cotton has excellent sound-absorbing qualities, and EcoShield meets the same acoustical performance of the Titus line of fiberglass-lined products.
·        Thermal protection: Outstanding insulation performance assists in conserving energy, without the potential health concerns associated with traditional fiberglass insulation.
·        High air-erosion tolerance: EcoShield meets the same standards as fiberglass. ASTM C1071.
·        Resists microbial growth: Treated with a patented EPA-approved fire retardant that limits fungus and mold growth. ASTM C1338, G21, and G22.
·        Resists dirt, debris, damage, and moisture: The durable non-woven facing provides resistance to dust, dirt, debris, moisture, and is available with foil facing as well.
·        No itch or skin irritation: Constructed of natural cotton fibers containing no harmful irritants and is safe to handle.
·        Exceeds Class A - Flame/Smoke: Surpassed Class A standards of 25/50 with actual EcoShield results being 5/10. ASTM E84.
·        Non-toxic: Patented fire-retardant treatment does not emit toxic fumes upon exposure to flame.

Airstream Surface

The Ecoshield surface that is exposed to the air stream is overlaid with a durable, fire-resistant facing that also provides additional strength. The liner facing is not only available in the black matte facing, but in foil facing as well in both ½” and 1” thicknesses. Ecoshield eliminates outgassing or Volatile Organic Compound (VOC) concerns, and includes an EPA registered anti-microbial biocide for mold and fungal inhibition that ensures the facing is safe for you and the environment.

Indoor Air Quality 

People have become more concerned about their IAQ when they have fiberglass in their HVAC systems. There has been a growing a trend toward eliminating fiberglass from the airstream.
Many owners and engineers require alternate liners in terminals and ductwork. Options for liners other than fiberglass are as follows:
·        Fibre Free™
·        SteriLoc™
·        UltraLoc™
·        EcoShield™

These liners remove fiberglass from the airstream, but there are financial/acoustical costs associated with them. Not having a liner would obviously be the least expensive of the options, but it would result in the highest acoustic penalty. Insulation is an excellent attenuator of HVAC sound.
Fibre Free™ is the least expensive of the liner options, but would increase the sound of the system by approximately 2 to 3 dB in each octave band.
SteriLoc™ covers the fiberglass fibers with foil scrim. They are a slightly higher cost alternative, but increase the sound of the system by approximately 4 to 6 dB in each octave band. There is also the potential that the foil scrim can get torn during installation, since it is a duct-board liner which is much denser and would expose the fiberglass to the airstream.
UltraLoc™, which sandwiches the fiberglass fibers between sheet metal, is the most expensive of the liner options and by far the heaviest. The sound increase of a double-wall terminal is dependent on unit design and airflow characteristics.
EcoShield™ allows you to take the fiberglass out of the airstream with no additional cost for the liner.
Suggested Specification
The terminal casing shall be minimum 22-gauge galvanized steel (20 gauge for fan-powered terminals), internally lined with ½-inch matte faced, natural fiber insulation that complies with ASTM C 1071 and NFPA 90A. The liner shall comply with ASTM G21 and G22 for fungi and bacterial resistance.
(Liner facing and thickness can be replaced in the above specification text to meet the different EcoShield types.)

Fan Filter Diffusers - The Solution for USP 797 and USP 800 Pharmacies

Fan filter diffusers (FFD) were introduced to the market in 1984 as a new solution in cleanroom applications. In situations where the use of conventional ducted modules is impractical or the air supply has insufficient static pressure to move the air through a HEPA filter, fan filter diffusers provide an excellent alternative.

In cleanroom design, the primary factor is contaminant removal and the cleanliness level, so moving the air is a major challenge. The volume of recirculated HEPA filtered air, including conditioned air to handle high cooling loads that are typical of many cleanrooms, can range from less than twenty to more than five-hundred air changes per hour. Fan filter diffusers are designed to address this situation by producing a laminar or unidirectional flow of clean air traveling downward at a velocity of 90-feet per minute, as measured 6” below the filter face.

Cleanroom manufacturing processes require a high level of air filtration to protect the raw materials and the end product from particulates that can damage the product or cause it to fail in use. Utilizing fan filter diffusers in cleanrooms prevents the infiltration of contaminants and also provides for the removal of particles generated by people and equipment in the work space. Typical cleanroom applications that utilize fan filter diffusers include:

  • Semiconductor Manufacturing 
  • Pharmaceutical Manufacturing 
  • Medical and Dental Device Manufacturing 
  • Digital Device Manufacturing 
  • Food Processing Plants 
  • Computer Manufacturing

Titus’ Fan Filter Diffusers … Low Energy, Low Sound and Low Profile

Titus offers a complete line of fan filter diffusers that can be used for new design or upgrading existing cleanroom environments. Each Titus FFD is a self-contained fan filter module that includes HEPA or ULPA filter, pre-filter, and fan speed control. Air circulation is maintained by using a lightweight, forward-curved fan, powered by a 120V or 277V 60Hz motor. Motor speed is adjusted by the solid-state speed control that is mounted on the top of the housing. Patented baffling technology ensures uniform airflow across the filter face and attenuates sound for one of the quietest fan filter diffusers in the industry. The room side replaceable option (R) provides quick and efficient replacement of the HEPA or ULPA filter while the diffuser remains in place. Room side replaceable diffusers are ideal for plenum areas with limited space or applications that require frequent filter changes.

Titus’ fan filter diffusers are also available with an electrically commutated motor (ECM) option. These units dynamically adjust themselves to maintain the set airflow, compensating for changes in static pressure, filter loading or other local conditions. Titus fan filter diffusers with an ECM can easily maintain cleanroom air levels exceeding the Institute of Environmental Sciences and Technology’s recommended practices. Airflow is maintained so constantly and consistently that the need for future balancing is greatly reduced. The ECM option, along with the patented baffling system and forward curve fan, makes Titus fan filter diffusers intelligent, energy efficient and ultra-quiet.
