FlexLine Flexible fabric products manufactured for mine and tunnel ventilation. Lightweight, flexible, histrength, durable, easy to handle and capable of quick installation.
MineDuct EP Ventilation s MineDuct Spiral is an extremely durable flexible ducting product used in negative pressure ventilation or as elbows in positive pressure ventilation systems. MineDuct is manufactured in diameters from 8 to 72 (200mm to 1800mm) in standard section lengths of 25ft (7.5 metres). The diameter of MineDuct and distance between the spiral wire helix (pitch) determine the negative pressure capacity. MineDuct is offered in a range of pitch options from 2 to 6 (50mm to 150mm).
MineVent q u a l i t y m a ke s a d i f f e r e nc e Engineered Performances MineVent high pressure ventilation ducting is used worldwide to supply positive pressure ventilation for mines and tunnels. MineVent is produced in standard diameters from 12 to 120 (300mm to 3050mm) in section lengths up to 1,640ft (500 metres). EP Ventilation s extensive line of PVC extrusion coated fabrics are designed and produced in -house to meet the demands of underground ventilation. Our PVC fabrics offer exceptional pressure capability, abrasion and tear resistance (see Fabric Specifications). Engineered Performances entire line of products meet international Flame Resistance standards such as NRC, DIN, MSHA. Anti -Static coated fabrics are also produced and certified to international standards for low surface resistivity as required by coal mines and gaseous tunnels. EP Ventilation s MineVent is complimented with a selection of hanging accessories and levelling wires for Drill & Blast mines and tunnels. Our fabric suspension design is integral to the MineVent and provides consistent linear support along the entire specified length. This design prevents sagging from weight and provides improved airflow as a result. A-4 Suspension Hook Suspension EP Ventilation also offers MineVent vertical shaft ducting that is fully supported on cables with hardware engineered to minimize install time.
MineVent q u a l i t y m a ke s a d i f f e r e nc e Engineered Performance s MineVent high pressure ducting is designed to perform in the world s most technical ventilation applications. Our experience is consistent with international standards such as SIA196 in recommending a safety factor of 10 for the ventilation duct s maximum working pressure relative to the duct s burst pressure. Working pressures beyond the safety factor of 10 are possible but not recommended due to increase in leakage, power consumption and the capital cost Engineered Performance s MineVent PRESSURE CHART EP Ventilation can assist in the design of your mine ventilation system and provide recommendations on a complete system including Fan s, Ducting and accessories. Our system design recommendations are focused on worker safety, maximized air flow to the face, low leakage at ducting joints, minimized power costs, as well as optimized fan arrangements and sound attenuation.
TwinDuct EP Ventilation s TwinDuct oval ventilation ducting is suitable for shorter runs up to 1000 metres (3,280ft). TwinDuct is designed to replace MineVent round flexible ducting in tight headings that require additional headroom with maximum air flow. TwinDuct offers 20% improvement in headroom with its unique design that decreases damage to the ducting and allows engineers to maximize the size of underground equipment with out decreasing the size of ventilation ducting. A full range of oval to round transitions are available to accommodate your specific needs. Refer to EP Ventilation s Accessories information for more details. TwinDuct is available in diameters ranging from 18 to 60 (450mm to 1500mm) and standard section lengths up to 100ft (30 metres). Nominal Diameter Equivalent to Round TwinDuct Dimensions A B 18 / 460mm 21 24.75 13.50 24 / 600mm 28 33.25 18.00 30 / 750mm 36 43.25 22.50 32 / 800mm 38 45.00 24.00 36 / 900mm 42.5 51.25 27.00 42 / 1100mm 50 60.00 31.50 48 / 1220mm 55 66.50 36.00 54 / 1400mm 63.5 76.50 40.50 60 / 1500mm 70 85.25 45.00 EP Ventilation s TwinDuct is complimented with our fabric suspension design that is integrally welded to the Twin Duct and provides consistent linear support along the entire specified length. This design prevents sagging from weight and provides improved airflow as a result. Grommet with Carabiner Suspension TwinDuct Suspension Configurations T 1 Suspension: Two suspension seams at 11 and 1 o clock position T 2 Suspension: Two suspension seams at 12 and 3 o clock position T 3 Suspension: One suspension seams at 12 o clock position
Couplings EP Ventilation offers the industry s most complete line of coupling options for MineVent, Twinduct, Oval, MineDuct Spiral and Accessories. High efficiency, leakproof couplings are critical to the successful installation of ventilation systems. EP Ventilation has soft coupling options for the ultimate in low resistance and leakage, and numerous options compatible with End Rings on the air inlet and air outlet of the ducting. EP Ventilation couplings are precisely engineered to reduce installation time and minimize air leakage at the joint. LOW RESISTANCE SOFT COUPLINGS: Zipper Coupling QuickSnap Coupling Hook & Loop Coupling END RING COUPLING WITH REINFORCING OPTIONS: B Flex PVC R Flex PVC Multi Clip Interlocking End Rings SD Metal Clamp High Pressure Metal Clamp
Accessories EP Ventilation offers a variety of accessories to complement our MineVent, MineDuct and TwinDuct product lines. Standard length accessories are engineered according to best practices for underground ventilation. Manufactured with Yellow Hi Strength X45 fabric (21 oz/yd2), standard length accessories are designed to provide smooth airflow within the accessory, reducing turbulence and damage to the accessory caused by potential flutter. Standard length accessories offer premium performance and product life in the most challenging underground environments.
