Operation Temperature: 40°F to 125°F. 1 x Iron Manganese filter. Filter size 19 7/8 inch x 4.5 inch. Thick Wall Coconut Base Carbon Filter Media, designed For maximum contact between the water and Iron sand. 5 Micron Nominal filter membrane included to prevent iron sands to pass from the filter to your drinking water. Operation Temperature: 40F to 125F. Iron manganese media, used for removing soluble iron and / or manganese as well as hydrogen sulfide from well water supplies, is a purple-black filter media processed from ceramic zeolite granule. Iron manganese can be used in a completely closed pressure system with no aeration or re-pumping, or in an open gravity filter system. The most common methods of operation are continuous regeneration, which is recommended for predominantly iron water. This filter is designed to provide an easy and effective method of reducing iron from water, which greatly improves the taste of your water as well. It helps to eliminate the orange and brown stains often found in toilets, sinks, Etc….. It also reduces the possibility of damage to pipes and water heaters and reduces up to 3 ppm dissolved iron. Note: Customers are advised to use a “sediment filter” as a pre-filter and a “CTO filter” as a post-filter to extend the life of the “Iron Manganese” replacement cartridge as the Iron-Manganese filter woven gets clogged fast if not protected by a sediment filter first. Also, customers might experience a slight pressure drop in water output (the minimum inlet pressure for the iron-manganese system is 60 psi). Rest assured this is normal and a part of the functioning of the media cartridge. Material Safety Data Sheet. Excessive concentrations of a nuisance dust may cause nuisance condition such as coughing, sneezing, and nasal irritation. Large oral doses may cause irritation to the gastrointestinal tract. Not expected to be a health hazard from skin exposure. May cause mild irritation and redness. No information found, but presumed to cause mechanical irritation. Aggravation of Pre-existing Conditions. Remove to fresh air. Get medical attention for any breathing difficulty. Not expected to require first aid measures. If large amounts were swallowed, give water to drink and get medical advice. Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation develops. Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention if irritation persists. Not considered to be a fire hazard. Not considered to be an explosion hazard. Use any means suitable for extinguishing surrounding fire. In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal. Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product. Exposure Controls and Personal Protection. (NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible, a half facepiece particulate respirator NIOSH type N95 or better. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. Wear protective gloves and clean body-covering clothing. Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area. Physical and Chemical Properties/ Characteristics. Appearance: Black Nodular Granules, Sand-like in Appearance.
