Heavy Duty Central Vacuum System Attachment Kit CV78PRO CV78PRO-DC Direct Connect Hose
This model of the CV78PRO kit is the Direct Connect hose style, sub model -DC. Our Direct Connect Heavy Duty attachment group includes a new lightweight crush-proof 30ft hose with a one-step connection cuff for powered wall plates to provide electricity to the premium power brush.

This type of connection fits only Direct Connect wall valves where the CVS wall plate supplies the 120 Volts to the power nozzle through mini-pin connectors. Wall valve brand names using this type of hose include the "Hayden Super Valve," "Vaculine ElectraValve" and Nutone's Super Valve. Our universal Direct Connect hose is designed to work with all direct connection valves on the market.

The new direct connect plates are preferred for new installations where carpet cleaning with a powered nozzle is required. When installing these plates you wire the standard 24V low voltage signal wire as you do with all wall valve installations, and also wire 120 Volt Romex© cable directly to the valve where it is tied into the receptacle.   Heavy Duty Central Vacuum System Attachment Kit CV78PRO

This allows you to just plug in the hose to make all 3 connections at once (Suction, Low Voltage, High Voltage), eliminating the need to supply power to the brush from an electrical outlet.

Direct Connection wall valves are simple to use and easy to install, however in most locations you will need to have a qualified electrician install them due to local code requirements. The CV78PRO series is also available in model CV78PRO-PT (see link at bottom of this page) with a pigtail Universal connection.

The Heavy Duty Commercial Powered Brush
When vacuuming with a powered brush one premise holds true: Faster is Better. Unlike its domestic competitors the European manufactured Lindhaus commercial power brush uses a geared belt drive and independent brush motor to drive their brush at over 5,000 RPM.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO That is nearly twice as fast as most power brushes. The unique brush roll is driven at this speed consistently during cleaning, allowing our nozzle to surpass all conventional flat belt drive products. The Lindhaus PB14 PRO is a true Commercial Powered Brush with a widepath nozzle, a full width of 380mm and a cleaning path of 14 inches.

The Lindhaus PB14-PRO nozzle is made for heavy duty and critical cleaning applications. The PB14-PRO is not offered by those distributors whom offer only systems for cleaning residential or light duty applications due to it's over engineering and higher price than most standard power nozzles. The standard duty Lindhaus PB power brushes are great nozzles for residential applications, but differ a great deal in design from the PB14-PRO. The PB14-PRO is a derivative of an industrial vacuum, the Lindhaus RX series, and includes many advanced features for high usage applications.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The Lindhaus PB-PRO power nozzle uses the geared drive system for unsurpassed performance. Geared belt drive systems offer unsurpassed cleaning performance for carpeted floors. If geared belt drive is so superior to flat belts, why does not every vacuum use a geared belt? This is a great question; the answer is that the ability to drive a brush at 5,000 RPM is a complicated procedure. First, you must balance the rotating brush to such a high degree that special equipment is required to do so. Otherwise an inferior quality brush would become damaged by the additional stress placed upon it rotating at such a high speed. Other parts must also be able to work within these tolerances, such as the bristles, bearings, pulleys and belt.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO Most all domestic vacuums use a single flat or round belt. This low-tech approach is cheap to manufacture, and adds more consumables to the vacuum (after sales service). When using a conventional vacuum, the moment the brush touches the flooring, slippage occurs. After 10 -15 hours of use, the heat and wear on the belt has weakened it and belt slippage increases; up to 50% of the rotational speed is lost.

Remember again, Faster is better. The geared belt drive also provides an additional benefit that is not found in most flat belt nozzles; excellent edge cleaning on both side of the brush. Thanks to the narrow width of the geared belt the bristles at the end of the brush are closer to the edge than regular power nozzles.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The geared belt of the PB-PRO (shown above colored red) is synthetic, made of neoprene and is fiberglass reinforced. Rubber is not needed because the belt does not stretch into place or require tension to spin the roller. The PB-PRO belt does not stretch out and does not require replacement like standard flat belts and is warranted for 3 years, and will last much, much longer. The bearings are sealed true commercial precision bearings, not the usual throw away bearings as used in most domestic vacuums.

The bearings are matched by the manufacturer for the speed and load of the application. The bearing holders are also unique to the PB-PRO and are made from cast aluminum. Most power nozzles use plastic end caps to hold the brush which mount into a plastic base. The problem is that most times the end of the roller will become tangled in threads, hair and carpet fibers which become heated by friction then melt the end of the roller and the base of the nozzle.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The PB-PRO end caps are made from cast aluminum and use o-rings to seal dirt, dust and threads away from the bearings which prevent damage to the brush roll and base structure. To reduce noise and vibration large rubber caps cover the brush bearings so the transfer of power from motor to brush is smooth and quiet.

The bristles on the brush roller of the PB-PRO are also commercial quality. The bristles are rated at 600 hours of use before failure. That's 6 - 10 times the life expectancy of domestic brushes. Considering that the brush roll is the only wear item of the PB-PRO you can see the low cost of maintenance for the PB-PRO. Other quality Power Brush features include convergent bristles, which means two rows of brushes are always touching the floor at one time, pulling everything to the center. The funnel shaped, center mounted brush nozzle intake with a geared belt is also unique to the PB-PRO.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The PB-PRO uses an electronic logic circuit that monitors the brush speed, constantly checking thousands of times per second for a possible overload. On most domestic vacuums this is not required, the brush simply does not spin fast enough, nor is there any direct drive on a flat belt system. This same logic circuit also alerts you via LED lights on the power nozzle when the brush is set too low. No more guessing if the vacuum is adjusted correctly, no more wondering if it is time to replace the belt.

How many times have you inadvertently vacuumed up a throw rug or article of clothing? In a normal vacuum, you at least break a belt, and possibly burn out the motor. With the logic circuit in the PB-PRO, the brush stops and signals the user with a red light. This allows you to unplug the machine and remove the object from the nozzle before damage can be done. Plugging the power brush back in automatically resets the circuit and you're ready to clean again.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO The nozzle connector of the PB-PRO is a double swivel that articulates both up and down, and side to side for complete control. The button locking connector fits a standard 32mm button lock wand for a positive locking connection and uses a release pedal to recline the nozzle into a cleaning position. The front and belt side of the nozzle are wrapped with a non-marring furniture guard to prevent damaging walls and baseboards and the beltless edge cleaning side features baseboard rollers. Only found on the PB-PRO the baseboard rollers are made from nylon and vertically mounted in a metal housing. When cleaning against a wall or cabinet the rollers help the nozzle to glide down the wall providing excellent edge cleaning without snagging.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO All four wheels of the PB-PRO are covered with a soft vinyl tire which protects the floor and provides excellent tracing on floors of all types. All four wheels are mounted on metal axels that provide for extended usage and wear resistance over the more common plastic wheel mounts. The PB-PRO cleaning shoe (opening for the brush) was also redesigned from the domestic power brush and is covered with stainless steel plates and carpet protectors. The stainless steel plates prevent damage to the bottom of the nozzle that is common with high or rough usage. Standard power brushes use plastic bottom plates that can become damaged when banged into heavy furniture or dragged over door thresholds.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO Another feature exclusive to the PB-PRO is the side entry brush roller. In other power brushes the complete nozzle must be disassembled to remove the brush roller from the housing for service or replacement. The PB-PRO's unique side entry roller housing features a removable door that slides off the nozzle and allows you to remove the roller from the nozzle without the use of any tools and without taking apart the nozzle base. This exclusive feature allows cleaning crews to service the PB-PRO in the field, on the job without having to return to a service center for cleaning or maintenance.

Heavy Duty Central Vacuum System Attachment Kit CV78PRO Yet another feature exclusive to the PB-PRO is the filter door with removable and washable foam filter. The filter is mounted on the back of the nozzle housing and protects the brush motor by filtering the air that is pulled into the nozzle for cooling.

Internal features of the PB-PRO include a cushioned motor mount for less noise and vibration, solid state circuit board, steel wear plates in the pivoting nozzle connector and a micro switch that automatically shut down the power brush when the handle is locked in the upright position. Despite it's impressive feature set using the PB-PRO is simple for anyone.

You need only connect the PB-PRO to the cleaning wand and plug it in. The carpet height adjustment is designed to clean 90% of carpet types set in the middle of its range and will require no further adjustment. Heavy Duty Central Vacuum System Attachment Kit CV78PRO The brush indicators will monitor the nozzle while in use with a green light and alert you to any problems with a red light. The PB-PRO is designed for high usage and built to take the rough use of service work. Perfectly suited to cleaning large offices or commercial buildings, restaurants and other areas with large carpeted floor spaces. The PB-PRO is equally well suited to cleaning the average home and will perform reliably for many years.
