PF-1 PREFILTERS- VANE PUMP SYSTEMS

Five different filters are used on these Spectra Watermakers to make sure that no damaging foreign materials enter the system. There are four filters in the system to clean the feed wa- ter of abrasive materials while the system is in operation, and a fifth filter that prevents the entrance of chlorine during fresh water flushing.

During normal operation the feed water is filtered in two stages. First it enters a fine mesh metal sea strainer then passes through a fifty micron pleated cellulose filter. These protect the vane pump from damage due to abrasion from silt and hard shelled plankton found in the feed water. After passing through the pump the feed water enters the filter housings contain- ing 20 and 5 micron elements. These filters remove very fine particles which could damage the Clark pump and which would shorten membrane life. Note: On Mark two systems there is no 50 micron filter and the 20 and five are before the feed pump.

Cleaning schedules will vary widely depending on how and where the system is used. If large amounts of feed water are run through the system in a relatively short period in bio- logically fertile near shore waters, the prefilters will plug up, the pressure drop across the filters will rise, product production and quality will drop, and the system will sense plugged filters and give a service prefilters or check strainer alarm if so equipped. Plugged filters can be cleaned several times by soaking in a bucket, towing behind the boat at moderate speeds, or hosing them off.

When operated only an hour or two a day in inland or near shore waters, the trapped plank- ton will begin to decay in the filters long before the elements plug up, and the bacteria in- volved in the decay will cause a “rotten egg” smell in the product water. This decay will set in overnight in tropical waters, or after a week or two in high latitudes. If handled gently and changed regularly before they get too smelly, filters in this service can last through doz- ens of cleanings.

In crystal clear blue water conditions the filters may need to be cleaned much less frequently.

The charcoal filter used in the fresh water flush system will not plug up unless you have some incredibly dirty domestic water in your boat. About six months after installation the charcoal filter element will lose its effectiveness at removing any membrane damaging chlo- rine which may be present in domestic water. Charcoal filter elements must be replaced every six months if there is ANY chance that chorine could be introduced into the flush wa- ter. Charcoal filter elements cannot be cleaned.

To ensure that filter elements fit properly and remove chlorine effectively, they should be purchased at factory authorized dealers. Our element part number is FT-FTC-XX. The last two digits indicate the micron rating, e.g. FT-FTC-05 is for a 5 micron element. Charcoal elements are FT-FTC-CC.

Newport 400 specifications

The Spectra Watermakers Newport 400 is a state-of-the-art desalination system designed for yachts and boats seeking reliable and efficient freshwater production. This innovative watermaker is known for its compact design, high performance, and user-friendly features. With the ability to produce up to 400 gallons of freshwater per day, the Newport 400 is ideal for extended cruising, offshore adventures, or as a backup water supply.

One of the standout features of the Newport 400 is its patented Spectra Reverse Osmosis technology. This advanced system harnesses the power of reverse osmosis to remove salt and impurities from seawater, ensuring the production of clean and safe drinking water. The Newport 400 operates with exceptional energy efficiency, requiring significantly less power compared to traditional watermakers. This is particularly beneficial for boats relying on limited energy sources like solar panels or generators.

The Newport 400 is engineered for ease of operation and maintenance with a user-friendly control panel. Operators can easily monitor key parameters such as water output, pressure, and system status. The intuitive interface makes it simple to adjust settings and troubleshoot potential issues. Additionally, the system is constructed from high-quality corrosion-resistant materials, ensuring durability and longevity in harsh marine environments.

An impressive characteristic of the Spectra Newport 400 is its ultra-quiet operation. This watermaker is designed to minimize noise, making it perfect for use in the close quarters of a yacht without disturbing the peace on board. The integration of advanced technologies further enhances its performance, including a sophisticated water pre-filtration system that reduces the risk of membrane fouling.

The Newport 400 is also designed with versatility in mind. It can be easily integrated into various onboard systems, allowing for simple installation and operation. Its compact size means it can fit into tight spaces on smaller vessels without sacrificing performance.

In summary, the Spectra Watermakers Newport 400 is a reliable, efficient, and quiet solution for generating freshwater in a marine environment. Its advanced reverse osmosis technology, ease of use, and robust construction make it an ideal choice for boaters seeking independence from shore-based water sources. Whether for leisurely cruising or serious ocean voyaging, the Newport 400 stands out as a top-tier watermaker for modern maritime adventures.
