Characteristics of HY-F3 dental unit
HY-F3 dental chair is suitable for left-handed users and can be freely switched between left and right hands.

The HY-F3 uses an integrated cast aluminum alloy bottom plate. Because the HY-F3 dental chair was designed from the beginning to take into account another group of dentistry, left-handed people, when compared to the E60 dental chair, the HY-F3 chassis is larger. Traditionally, because most of the tools and equipment are designed for right-handed people, someone left handed will encounter certain problems in handling the dental chair. Therefore, the design of this dental chair has been thoughtfully considered with left handed people in mind.

It is in consideration of the needs of the left-handed user that HIROL has studied and designed a dental chair that can be used by the left-handed and right-handed in the same working area. The F3 dental chair uses a rear connection type and uses a double joint design at the connection site. In addition, the instrument table can be rotated 180 degrees using a pull-down type, including a rotatable box.

With the above solutions, the F3 dental chair can be moved smoothly by using the mobile device table, case and auxiliary stand, which makes it convenient for both left-handed and right-handed users.

• Fully computer controlled operation: the waterproof and dust resistant touch buttons have a service life that is 5 times longer than traditional buttons. The dental chair has automatic reset, patient position, and special memory functions. The main control board and sub-control board are both equipped with computer keys and an instrument tray mat.
• The power system uses a Danish-branded linear silent motor, and the overall height adjustment time is within 7 seconds. The power system does not require maintenance.
• The HY-F3 integrated dental unit has an angle compensation function, meaning dentists can adjust and lock the chair's headrest with just one hand.
• The dental chair is wide, and made with an American style sewing technique with environmentally friendly, ultra-fiber leather. In addition, the leather pad and body are connected with buckles, making them easy to remove.
• The dental chair is equipped with a double armrest, with the outer armrest capable of opening as needed. The chair's balancing arm uses a pressure lock design, and the arm joint uses a pull-down plane bearing, allowing users to freely push/pull the instrument as needed.

• The handpiece is placed underneath, and is equipped with a water adjustment on each handpiece. The dental chair is equipped with a low-voltage dental X-ray viewer with a balanced luminosity, making it easy for dentists to carry out clinical treatment.
• The chair has a three-way syringe (water, gas, water mist) for use with cold or hot water, and a head that can be removed for easy cleaning and disinfection.
• The chair is equipped with an LED intraoral camera with an adjustable intensity to effectively avoid doctor eye fatigue.
• The dental chair has a built-in pure water system that can also switch to tap water usage.

• Four-handed frame with a wide moving range: There are 15 function buttons, including computer keys that control operation of the flushing spittoon, rinsing, the automatic resetting of the dental chair and the closing of the patient position and oral light. In addition, the chair is equipped with a suction saliva ejector valve, which has an intensity control button in order to facilitate control of the suction flow.
• This part has a weak suction saliva ejector valve, which features an intensity control button in order to facilitate control of the suction flow.
• This department also has a three-way syringe (water, gas, water aerosol) and a removable head for easy cleaning. It is also equipped with a vacuum filter.

Safety device
When an emergency situation is encountered during the treatment, the operation of the emergency stop machine includes lifting the assistant's instrument tray, pressing any key of the doctor's or assistant's operating panel and depressing the foot switch.

When the treatment table encounters an obstacle during the descent, the dental chair will stop falling and automatically rise. This can prevent the dental chair from being damaged by obstacles.

Spittoon
Integral removable spittoon, with a smooth body that is free of sharp edges: It can rotate up to 210 degrees for easy cleaning and disinfection. In addition, the waterflow is smooth, with the water speed being no less than 4L/minute.
